|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. You can apply it to
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
them if you wish), that you receive source code or can get it if you
|
||||
want it, that you can change the software or use pieces of it in new
|
||||
free programs, and that you know you can do these things.
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. You must make sure that they, too, receive
|
||||
or can get the source code. And you must show them these terms so they
|
||||
know their rights.
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing

to distribute software through any other system and a licensee cannot
|

impose that choice.
|

|
||||
14. Revised Versions of this License.
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU General Public License from time to time. Such new versions will

9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
NO WARRANTY
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||

||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

This is a list of random notes for GRUB maintainers. If you are not a
|
||||
maintainer, you need to ask maintainers to do these instead of doing
|
||||
these yourself.
|
||||
|
||||
How to update the online manual: (FIXME: this is obsoelete)
|
||||
1. Copy docs/*.texi (excluding "multiboot.texi") to fencepost.gnu.org.
|
||||
2. Make a symbolic link from ~mohit/gnudoc/gnudoc_template to the
|
||||
directory under which *.texi were copied, if the link isn't present.
|
||||
3. Run ``~mohit/gnudoc/gendocs.sh grub "GNU GRUB Manual"''.
|
||||
4. Copy the contents of the directory ``manual'' to
|
||||
gnudist.gnu.org:~ftp/gnu/Manuals/grub-VERSION (VERSION is, for
|
||||
example, 1.0).
|
||||
5. Run ``ln -sf grub-VERSION grub'' in gnudist.gnu.org:~ftp/gnu/Manuals.
|
||||
6. Run ``cd grub; ln -s grub.html index.html''.
|
||||
7. Verify the new online manual with a WWW browser.
|
||||
8. Update manual.html by hand.
|
||||
|
||||
How to release a version:
|
||||
1. Check out the source tree from the CVS from scratch.
|
||||
2. Check if ``make distcheck'' succeeds.
|
||||
3. Run ``util/grub-image''.
|
||||
4. Check the resulted images, for example, using bochs.
|
||||
5. Copy grub-VERSION.tar.gz, grub-VERSION-i386-pc.tar.gz and
|
||||
grub-VERSION-i386-pc.ext2fs to fencepost.gnu.org:~ftp/gnu/grub.
|
||||
6. Move older files in that directory above to the directory ``old'',
|
||||
if you think they are eyesores.
|
||||
7. Post an announcement to bug-grub@gnu.org. It would be a good idea to
|
||||
send a carbon copy to bug-hurd@gnu.org and
|
||||
debian-hurd@lists.debian.org. If the announcement is for a stable
|
||||
version, you can inform info-gnu@gnu.org as well.
|
||||
8. Optionally, post an announcement to Freshmeat.net.
|
||||
|
||||
Legal issues:
|
||||
1. If a patch is not significant (in size), you don't have to care about
|
||||
the copyright.
|
||||
2. If a patch is significant, you shouldn't apply the patch to the CVS.
|
||||
Before doing that, you must ask the contributor to assign or disclaim
|
||||
the copyright. Send ``/gd/gnuorg/request-assign.changes'' or
|
||||
``/gd/gnuorg/request-assign.future'' to the contributor, and wait
|
||||
until the FSF finishes the legal work.
|
||||
3. You can check if a contributor has already assigned his/her copyright
|
||||
to the FSF by looking at ``/gd/gnuorg/copyright.list''.
|
||||
|
||||
What you should have in your mind:
|
||||
1. Don't add features unnecessarily! You may think it is a Good Thing to
|
||||
have more features, but you must be prepared for more burdens.
|
||||
DO THAT ONLY IF YOU BELIEVE THAT THE FEATURE IS ESSENTIAL.
|
||||
2. Don't break backward-compatibility! Don't apply any patch which could
|
||||
break existing features. Otherwise you would receive a lot of
|
||||
complaints. DO THAT ONLY IF YOU BELIEVE THAT THE INCOMPATIBILITY IS
|
||||
INEVITABLE.
|
||||
3. Write good code. Be not satisfied with ad hoc workarounds or quick
|
||||
hacks. NEVER WRITE BAD CODE.

NEWS - list of user-visible changes between releases of GRUB
|
||||
|
||||
New in 0.97 - 2005-05-08:
|
||||
* Fix the prototypes and the definitions of nested functions. This was
|
||||
required for gcc-4.
|
||||
* Implement a more robust workaround for buggy BIOSes which don't pass
|
||||
boot drive correctly (notably for HP Vectra).
|
||||
|
||||
New in 0.96 - 2005-01-30:
|
||||
* The command "fallback" supports mutiple fallback entries.
|
||||
* The command "savedefault" supports an optional argument which
|
||||
is the number of next boot entry or the special keyword `fallback'.
|
||||
* New utility "grub-set-default".
|
||||
* New section "Making your system robust" in the manual.
|
||||
|
||||
New in 0.95 - 2004-06-13:
|
||||
* Add support for ReiserFS 3.
|
||||
* Fix support for FreeBSD 5.
|
||||
* Support ATARAID for Linux in the grub shell and grub-install.
|
||||
* Add CDROM support for El Torito with no emulation mode. You can use
|
||||
(cd) as a CDROM drive in the config file.
|
||||
* Option --no-mem-option is implied for Linux 2.4.18 and newer.
|
||||
* Add support for UFS2.
|
||||
|
||||
New in 0.94 - 2004-01-25:
|
||||
* Support building on x86-64 with gcc -m32.
|
||||
* Use a BIOS call to turn on/off Gate A20. This should solve various
|
||||
problems related to Gate A20 in modern BIOSes.
|
||||
* Add a workaround for buggy BIOSes (notably HP Vectra series) which
|
||||
don't pass the boot drive correctly.
|
||||
* Display "GNU GRUB" instead of "GRUB" in the menu.
|
||||
* Add support for QNX RTP into the grub shell.
|
||||
* Add support for the initrd max address of a kernel header in Linux.
|
||||
* Support 32 bit and 64 bit dev_t.
|
||||
* Add support for an install device in GRUB's notation with no
|
||||
parenthesis (e.g. grub-install hd0).
|
||||
* Improve the manual a lot.
|
||||
|
||||
New in 0.93 - 2002-12-08:
|
||||
* Define the behavior of the boot loader when the load end address is
|
||||
zero and the bss end address is zero in the Multiboot Specification.
|
||||
Also, add the support into GRUB.
|
||||
* Finally, we have a Bug Tracking System! Now the preferable way to
|
||||
report bugs is to use the BTS rather than sending e-mail to bug-grub.
|
||||
See <http://bugcomm.enbug.org/?project=grub&mode=project>, for more
|
||||
details.
|
||||
* The appendix "FAQ" in the manual is removed. See the GNU GRUB FAQ on
|
||||
the web <http://www.gnu.org/software/grub/grub-faq.html> instead.
|
||||
* The terminal handling code is rewritten radically, and many bugfixes
|
||||
are made at the same time.
|
||||
* The command "color" is effective even in the command-line.
|
||||
* The command "terminal" takes two new options, ``--no-echo'' and
|
||||
``--no-edit''. If you specify ``--no-echo'', GRUB won't echo back
|
||||
input characters. If you specify ``--no-edit'', GRUB will disable the
|
||||
BASH-like editing feature. These options are useful when using an
|
||||
intelligent terminal (such as the comint mode in GNU Emacs).
|
||||
* The utility ``grub-md5-crypt'' prompts to retype a password and checks
|
||||
if the passwords match.
|
||||
* Support for booting Linux is rewritten, so GRUB now supports
|
||||
large-EBDA systems.
|
||||
* The menu interfaces supports Page Up, Page Down, and Right Key.
|
||||
* New command "terminfo", for vt100-incompatible terminals.
|
||||
* New options, ``-D'', ``-g'' and ``-m'' are supported for FreeBSD.
|
||||
|
||||
New in 0.92 - 2002-04-30:
|
||||
* The command "displaymem" uses only hex digits for consistency.
|
||||
* The netboot code goes back to the progress bars instead of dots, for
|
||||
the notation of data transfers. And, that is displayed only in debug
|
||||
mode, that is to say, nothing is displayed by default. Remember that
|
||||
you can turn on debug mode via the command "debug".
|
||||
* The command "help" doesn't show all the available commands by default,
|
||||
when no argument is specified. Rarely used commands (such as
|
||||
"testload") and useless commands in interactive use (such as
|
||||
"savedefault") are hidden. If you want to see help messages for those
|
||||
commands, specify the new option "--all".
|
||||
* A built-in, `more'-like pager is added. When a command prints too many
|
||||
lines to fit the screen, GRUB waits until you hit return key. This
|
||||
feature can be turned off by the new command "pager".
|
||||
* The command "terminal" accepts a new option, "--lines=LINES". You can
|
||||
set the maximum number of lines arbitrarily with this option. If you
|
||||
don't specify it, the maximum number will be 24.
|
||||
* The command "terminal" accepts another new option, "--silent". You can
|
||||
suppress the "Press any key to continue" message with this option.
|
||||
* The mem= option for Linux is recognized and used to limit the maximum
|
||||
address of initrd.
|
||||
* A fallback entry is executed immediately after a default entry,
|
||||
without prompting a user's intervention, as the manual has ever been
|
||||
saying.
|
||||
* The utility ``grub-install'' makes sure that GRUB images have been
|
||||
written to a physical disk completely. To assist this feature, a new
|
||||
command "dump" is added.
|
||||
|
||||
New in 0.91 - 2002-01-21:
|
||||
* Support for Linux DAC960 is added.
|
||||
* JFS and XFS support is added.
|
||||
* The commands "hide" and "unhide" support logical partitions.
|
||||
* The utility ``grub-install'' supports NetBSD.
|
||||
* The network support is updated to Etherboot-5.0.5.
|
||||
* The manner of handling the preset menu changes. In the previous
|
||||
implementation, the preset menu is used only when opening the
|
||||
configuration file failed. Now try to use the preset menu first. And,
|
||||
if the configuration file is available, it is read after readoing the
|
||||
preset menu. In this case, menu entries in the preset menu (if any)
|
||||
are overrided by the configuration file.
|
||||
* Diskless support is a bit changed. In the previous, GRUB set up a
|
||||
network automatically via a special function. In the current, the
|
||||
function is gone and the preset menu feature is used (i.e. just
|
||||
execute the command "bootp" as if you specified it in the preset
|
||||
menu). This has no impact against most users, but you should take care
|
||||
if using the preset menu for your own purpose, because GRUB doesn't
|
||||
call "bootp" implicitly when the preset menu is used explicitly. In
|
||||
this case, you would probably need to insert commands to initialize a
|
||||
network into your preset menu.
|
||||
* Important bugfixes are made for ReiserFS, APM, TFTP, LBA, etc.
|
||||
|
||||
New in 0.90 - 2001-07-11:
|
||||
* The command "setkey" resets key mappings, when no argument is
|
||||
specified.
|
||||
* Linux devfs support is added.
|
||||
* The utility ``grub-install'' accepts a new option, `--recheck'. If
|
||||
this option is specified, probe a device map, even if it already
|
||||
exists. You should use this option whenever you add/remove a disk.
|
||||
* The command "password" supports a md5 password if the option `--md5'
|
||||
is given. This command can now also be used to protect specific menu
|
||||
items with their own passwords.
|
||||
* New command, "displayapm".
|
||||
* New command, "md5crypt".
|
||||
* The new utility ``grub-md5-crypt'' is a frontend of the grub shell. It
|
||||
encrypts a password in MD5 format.
|
||||
* New commands, "testvbe" and "vbeprobe".
|
||||
* The configure script accepts a new option, `--enable-preset-menu'. You
|
||||
can embed an arbitrary configuration which will be used when Stage 2
|
||||
cannot open a real configuration file, with this option. The argument
|
||||
must be an existing file.
|
||||
* EZ-BIOS support is added.
|
||||
* Booting Windows from a logical partition is supported.
|
||||
* The example Multiboot kernel in the directory "docs" is built, if you
|
||||
specify the option `--enable-example-kernel' to the configure script.
|
||||
* New command, "ifconfig".
|
||||
* Linux software RAID support is added (only for RAID-1).
|
||||
* Hercules support is added.
|
||||
* The configure script now accepts `--disable-auto-linux-mem-opt', which
|
||||
has the same meaning as you specify the option `--no-mem-option' to the
|
||||
command "kernel".
|
||||
* Jump to the physical entry address of a Multiboot kernel when booting
|
||||
it up. The old behavior was to use the virtual one, regardless of the
|
||||
setting of the physical address.
|
||||
* The commands "bootp" and "dhcp" accepts a new option
|
||||
`--with-configfile', so that you can load a remotely specified
|
||||
configuration file automatically, like the network boot images.
|
||||
* VSTa filesystem support is added.
|
||||
* ELF symbol loading support is added.
|
||||
|
||||
New in 0.5.96 - 2000-10-04:
|
||||
* New commands, "reboot" and "halt".
|
||||
* New command, "hiddenmenu". You can hide the menu interface by default
|
||||
with this command.
|
||||
* You can specify `--no-mem-option' to the command "kernel", if you want
|
||||
GRUB not to pass a Linux's mem option automatically.
|
||||
* Now GRUB is compliant with the Linux/i386 boot protocol version 2.02.
|
||||
* The network support is updated to Etherboot-4.6.4.
|
||||
* Symlinks in ReiserFS are supported.
|
||||
* Add a workaround into the grub shell, so that it works fine even under
|
||||
Linux 2.4.
|
||||
* Add a new option `--stage2' into the commands "install" and "setup",
|
||||
to let the grub shell know what the file name of Stage 2 is under your
|
||||
operating system. You must specify the option correctly, if you cannot
|
||||
unmount the partition where GRUB images reside. We'd recommend _not_
|
||||
using those commands directly, but using the utility "grub-install"
|
||||
instead, because this is safer.
|
||||
* One violation against the Network Boot Image Proposal was found and
|
||||
fixed. So now the image `nbgrub' can work fine even with a card such
|
||||
as rtl8139.
|
||||
* Serial terminal support is added. The configure script accepts
|
||||
a new option `--disable-serial'. Unless it is specified, you can use
|
||||
two new commands, "serial" and "terminal" in the command-line and the
|
||||
menu. See the manual, for more details.
|
||||
* Preserve the possible magic number used by Windows NT in a MBR.
|
||||
* The command-line interface is switched to single-line editing mode.
|
||||
* Only for developers: the configure script accepts
|
||||
`--enable-serial-speed-simulation', which is useful when you want to
|
||||
simulate the speed of a serial device on a psuedo terminal.
|
||||
* Also only for developers: you can specify an optional argument to the
|
||||
option `--hold' for the grub shell. The argument means how many
|
||||
seconds the grub shell should wait until diving into the main routine.
|
||||
* New command, "savedefault". Now you can save current entry number to
|
||||
your disk with this command and then you can set the default boot
|
||||
entry to it by the command "default saved".
|
||||
* Add a new option `--prefix' into the command "setup", so that you can
|
||||
specify the name of a directory which contains GRUB images. And, the
|
||||
behavior of this command changed slightly, that is, this command now
|
||||
searchs stage1 automatically under "/boot/grub" and "/grub", unless
|
||||
you specify the option `--prefix'.
|
||||
* The utility `grub-install' recognizes a separate boot partition
|
||||
automatically.
|
||||
* New commands, "partnew" and "parttype". You can modify partition
|
||||
tables with these commands.
|
||||
|
||||
New in 0.5.95 - 2000-06-27:
|
||||
* NetBSD ELF kernel support is added. You have to specify the new option
|
||||
to the command "kernel". See below.
|
||||
* Added a new option `--type=TYPE' into the command "kernel". This
|
||||
option suggests what type of kernel you want to load. TYPE must be
|
||||
either of "netbsd", "freebsd", "openbsd", "linux", "biglinux" and
|
||||
"multiboot". Actually, this option will be necessary only if you want
|
||||
to load a NetBSD ELF kernel, because GRUB can automatically determine
|
||||
a kernel type in the other cases.
|
||||
* ReiserFS support is added.
|
||||
* Added a new option `--force-lba' into the command "install". This
|
||||
option disables some sanity checks for LBA mode (but not all). If you
|
||||
are sure that your machine supports LBA mode but GRUB doesn't work in
|
||||
LBA mode, you should specify it. It is necessary if your BIOS is too
|
||||
buggy. In the previous version, it was a compile-time option, but you
|
||||
don't have to recompile GRUB any longer.
|
||||
* Likewise, now the command "setup" and the script "grub-install" also
|
||||
accept `--force-lba' option. Specifying this option to "setup" or
|
||||
"grub-install" has the same effect as to the command "install".
|
||||
* The configure script doesn't accept the option
|
||||
`--disable-lba-support-bitmap-check' any longer. Use the option above.
|
||||
* The network support is updated to Etherboot-4.6.1. So now we have
|
||||
3Com59x and DEPCA drivers.
|
||||
* Now you can omit the configuration file argument to the command
|
||||
"password". If you omit it, then GRUB will just unlock privileged
|
||||
instructions (such as `c') when you enter a correct password.
|
||||
* The new command "lock" can be used to prevent end-users from executing
|
||||
arbitrary menu entries. This command will emit an error until the user
|
||||
enters a correct password.
|
||||
* Recognize the Linux extended partition type.
|
||||
* Pass a correct memory size to Linux and *BSD.
|
||||
* Diskless support is added. Now configure accepts --enable-diskless,
|
||||
and "make" will produce two additional images, ``nbgrub'' for Net Boot
|
||||
Image Proposal and ``pxegrub'' for Preboot Execution Environment. See
|
||||
the documentation, for more details.
|
||||
* The command "tftpserver" overrides a TFTP server address returned by a
|
||||
BOOTP server, a DHCP server or a RARP server.
|
||||
* Fix a serious bug about LBA support. It is possible that you don't
|
||||
disable the LBA support bitmap check any longer. Please send a report,
|
||||
if you must still disable it. We need to know if we should get rid of
|
||||
the option.
|
||||
|
||||
New in 0.5.94 - 2000-03-06:
|
||||
* Stage 1 supports both the LBA mode and the CHS mode.
|
||||
* The NetBSD and OpenBSD boot bug is fixed.
|
||||
* The more automatic installation command "setup" is added.
|
||||
* The command "embed" embeds a Stage 1.5 in the sectors after a MBR.
|
||||
* Support symbolic color name syntax in the command "color".
|
||||
* The grub shell loads the BIOS drive mapping information from a device
|
||||
map file if it is specified and can be opened. If not found, try to
|
||||
create it based on the guessed information.
|
||||
* NetBSD support in the grub shell is improved.
|
||||
* A simple checker for the format of a Multiboot kernel, ``mbchk'', is
|
||||
added.
|
||||
* The command "find" searches for a filename in all devices and print
|
||||
the list of the devices which contain the file.
|
||||
* The command "map" maps a drive to another drive so that we can
|
||||
chain-load some foolish operating systems (such as DOS) even if such
|
||||
an operating system resides at a non-first drive.
|
||||
* The command "setkey" maps a key to another.
|
||||
* The GRUB manual is rewritten, and now consists of three parts and
|
||||
appendices.
|
||||
* The command "ioprobe" detects what I/O ports are used for a BIOS
|
||||
drive.
|
||||
* OpenBSD support in the grub shell is improved.
|
||||
* The command "install" can now patch a Stage 2 with a different
|
||||
filename from "/boot/grub/menu.lst" even if a Stage 1.5 is used.
|
||||
* New program, ``grub-install''.
|
||||
* The command "blocklist" prints the blocklist notation of a file.
|
||||
* The command "chainloader" now accepts an option "--force", which is
|
||||
required if you want to chain-load a boot loader defective in the
|
||||
signature, such as SCO Unixware 7.1.
|
||||
* The netboot support is heavily rewritten, based on Etherboot-4.4.3.
|
||||
Most of the device drivers are stolen from it, so we now have many
|
||||
network drivers. See netboot/README.netboot for more details.
|
||||
* Now configure accepts the option `--disable-lba-support-bitmap-check'
|
||||
to ignore an incorrect LBA support bitmap returned by a buggy BIOS. If
|
||||
you are sure that your BIOS does support LBA mode but GRUB doesn't
|
||||
work in LBA mode, recompile GRUB with this option specified. You can
|
||||
check if GRUB accesses a drive in LBA mode by the command "geometry".
|
||||
* New commands "bootp", "dhcp" and "rarp" can be used to initialize a
|
||||
network device and get IP addresses from a network.
|
||||
* Long filename support in the FAT filesystem is added.
|
||||
* The command "cmp" compares each bytes in two files.
|
||||
|
||||
New in 0.5.93 - 1999-10-30:
|
||||
* ELF format of FreeBSD kernel is supported.
|
||||
* Support the partition ids for NetBSD and OpenBSD.
|
||||
* Exit from the grub shell just by pushing the key `q' in the menu.
|
||||
* New options for configure can disable some functions in Stage 2. See
|
||||
the output from `configure --help' for more information.
|
||||
* FAT32 support is added.
|
||||
* Minix fs support is added.
|
||||
* New commands "hide" and "unhide".
|
||||
* The character `=' after a command is not necessary any longer, but it
|
||||
is supported for backward compatibility.
|
||||
* The command "help" displays helpful information about builtin
|
||||
commands.
|
||||
* The command "geometry" displays the information of a drive specified
|
||||
and set the geometry to arbitrary C/H/S values if the optional
|
||||
arguments are used.
|
||||
* The command "configfile" loads a configuration file interactively.
|
||||
* The command "device" assigns a BIOS drive to an arbitrary filename in
|
||||
the grub shell.
|
||||
* The option `--no-floppy' force the grub shell to assume that there is
|
||||
no floppy, and the option `--probe-second-floppy' enables the probe of
|
||||
the second floppy drive.
|
||||
* Integrated the netboot support in the Dresden version of GRUB.
|
||||
* FreeBSD support in the grub shell is improved.
|
||||
* Killing (C-u and C-k), yanking (C-y) and manipulating the history
|
||||
(C-p and C-n) are supported.
|
||||
* The address argument for the command "install" is now optional.
|
||||
* Better completion support.
|
||||
* The command "cat" displays the contents of a file.
|
||||
|
||||
New in 0.5.92 - 1999-07-26:
|
||||
* Bug fixes (i.e. Stage 1.5 can work fine again).
|
||||
* The /sbin/grub stage2 simulator now works at least on GNU/Linux, and
|
||||
uses the Linux HDIO_GETGEO ioctl to determine hard disk geometry.
|
||||
* TAB not only lists filenames, but also completes a filename when the
|
||||
filename is unique.
|
||||
* Password is not echoed back, put an asterisk for each of input
|
||||
characters.
|
||||
* stage2_debug is removed, and the debugging features are added into
|
||||
stage2.
|
||||
* Color menu support.
|
||||
* New command "quit".
|
||||
* The man page for /sbin/grub.
|
||||
* All documents become Texinfo.
|
||||
* Linux video mode selection is supported.
|
||||
* The new Stage 1 `stage1_lba' supports LBA addressing mode.
|
||||
|
||||
New in 0.5.91 - 1999-03-14, Gordon Matzigkeit:
|
||||
* LBA and preliminary AWARD BIOS disk extension support.
|
||||
* Started docs/grub.texi.
|
||||
* /sbin/grub GUI now works (but it doesn't yet access disks properly).
|
||||
Run `configure --enable-sbin-grub' to build this program in the grub
|
||||
subdirectory.
|
||||
|
||||
New in 0.5.90 - 1999-03-01, Gordon Matzigkeit:
|
||||
* Bug fixes.
|
||||
* GRUB understands symlinks on ext2fs (but still not ffs).
|
||||
* Many source code and build cleanups to comply with GNU standards.
|
||||
|
||||
New in 0.5 - 1998-08-20, Erich Boleyn:
|
||||
|
||||
* Improved error messages in the stage1 to be strings (easier to read
|
||||
than the previous case of single characters), and removed any
|
||||
display in the case of no error (less confusing).
|
||||
|
||||
* New document describing error conditions and messages.
|
||||
|
||||
* Improved configure/build process.
|
||||
|
||||
* Made the early bootup interrupt-safe. Wasn't doing cli/sti when
|
||||
necessary sometimes.
|
||||
|
||||
* GRUB now shuts off the floppy before transferring control to any
|
||||
other programs/modules/loaders. (chain-loading doesn't matter here,
|
||||
just loading 32-bit modules/kernels)
|
||||
|
||||
* Fixed a few stupid bugs, including a several in the ext2fs code.
|
||||
|
||||
* Linux boot format support extended from just "zImage" to include
|
||||
"bzImage" and initial ramdisk (also called "initrd") support for
|
||||
both. "initrd" support is untested, but the critical parts were
|
||||
taken from a supplied patch and seem OK.
|
||||
|
||||
* Several new command features. See the command-listing for details.
|
||||
|
||||
New in 0.4 - 1998-03-19, Erich Boleyn:
|
||||
|
||||
* GRUB now correctly points ES:SI at a partition descriptor when
|
||||
chain-loading.
|
||||
|
||||
* Many minor bugs fixed (some in the build scripts).
|
||||
|
||||
* Intel MPS 1.4 config/check code is totally new, and the "syscmd="
|
||||
command is completely removed. Check command-listing for details.
|
||||
|
||||
Version 0.4-pre, Erich Boleyn:
|
||||
|
||||
* Reorganized docs, moved most "NOTE" items to a FAQ (with new entries
|
||||
as well).
|
||||
|
||||
* Now supports automatic decompression of any files loaded via the
|
||||
GRUB stage2 filesystem code. Simply compress the file using GNU
|
||||
gzip normally, then when loading, the GRUB internals will see the
|
||||
contents in the decompressed state... i.e. all GRUB functions
|
||||
operate normally as if it is the uncompressed file. An extra
|
||||
version of the "module" loading function has been added which
|
||||
disables this functionality if desired (in all the other cases, not
|
||||
decompressing doesn't make sense).
|
||||
|
||||
* Changed device strings used in filesystem code to more logical
|
||||
format. Added "relative" disk and partition capability, see
|
||||
command-listing and filesystem syntax description for details.
|
||||
|
||||
* "install=" command vastly improved. Also moved to non-debug area.
|
||||
Check command-listing and install documentation for details.
|
||||
|
||||
* Added several new commands: "rootnoverify=", "uppermem=", and a new
|
||||
debug command "displaymem". Check command-listing for details.
|
||||
|
||||
* Added versioning numbers (and subsequently broke compatibility with
|
||||
some of the previous code, so GRUB should be re-installed!).
|
||||
|
||||
* Added unattended booting support via new "fallback=" command.
|
||||
|
||||
* During debug probe of SMP configuration table compatible with Intel
|
||||
MPS 1.4 standard, GRUB now checks for a pointer in the EBDA.
|
||||
|
||||
* Using a "default=" entry greater than 11 caused the UI to do funny
|
||||
things (it didn't pre-scroll the list to the appropriate place).
|
||||
|
||||
* Reading files on FAT floppies had yet more problems related by many
|
||||
users of version 0.3 6/17/96. Again, all known problems fixed.
|
||||
|
||||
* "Extended" partitions now work (still cannot make an extended
|
||||
partition active with "makeactive" command).
|
||||
|
||||
* The build environment is greatly simplified, now using an
|
||||
autoconf-like "configure" script.
|
||||
|
||||
New in 0.3-19960617 - 1996-06-17, Erich Boleyn:
|
||||
|
||||
* Yet more documentation improvements.
|
||||
|
||||
* Known bugs in floppy operation fixed (12-bit FAT didn't work for
|
||||
most cases, and inserting other floppies didn't flush the filesystem
|
||||
cache).
|
||||
|
||||
* NASTY uninitialized pointer bug causing "raw" floppy operation to
|
||||
crash on several PCs is now fixed. This seems to have been the root
|
||||
cause of all of the compatibility problems that have currently been
|
||||
observed.
|
||||
|
||||
* debug-mode command added to automate most difficult step of
|
||||
installation for common cases (new install method #4).
|
||||
|
||||
* Testing "mini-debugger" now merged with command-line when "DEBUG"
|
||||
defined in compile (no SYSDEBUG option anymore). See description of
|
||||
commands in the command-line for details.
|
||||
|
||||
New in 0.3-19960602 - 1996-06-02, Erich Boleyn:
|
||||
|
||||
* Completed initial licenses.
|
||||
|
||||
* Initial filesystem documentation written.
|
||||
|
||||
* Block-list and FAT filesystems now work as documented (in
|
||||
particular, for the blocklist filesystem, shortcuts like "+1" for
|
||||
"0+1,512" now work correctly).
|
||||
|
||||
* Fixed several problems (old and new) in the various filesystems (for
|
||||
example, the ext2fs filesystem code is now much faster, as it caches
|
||||
some mapping blocks where it didn't at all before). Filesystem
|
||||
semantics are much more uniform as well (symbolic links and reading
|
||||
a directory as a file now return errors where it would silently fail
|
||||
before).
|
||||
|
||||
* "makeactive" now works for standard PC partitions on hard disks (not
|
||||
extended partitions... so any PC partition number above 3 will give
|
||||
a "no such partition" error). If a BSD sub-partition is is used, it
|
||||
will ignore it, and only use the primary PC partition number.
|
||||
|
||||
New in 0.3-19960520 - 1996-05-20, Erich Boleyn:
|
||||
|
||||
* Updated instructions (though still very sparse).
|
||||
|
||||
* New floppy probe (works much like the Linux floppy boot probe)
|
||||
attempts to find the size of a floppy in a drive. Might still need
|
||||
work! Please try on various floppy drives with various media!
|
||||
|
||||
* New floppy handler will claim a non-existent drive if the floppy
|
||||
disk isn't present in the drive. (for example, it won't be on the
|
||||
list of installed drives unless a floppy is present)
|
||||
|
||||
* Stage1 now compatible with both a hard disk MBR and the DOS BIOS
|
||||
parameter block (see "install/README" for more details on how this
|
||||
can be used).
|
||||
|
||||
* Block-list filesystem partially works, as described in the file
|
||||
"NOTES". Loading an a.out or elf kernel won't work with it, but all
|
||||
other filetypes pretty much should. (certainly chain-loading works
|
||||
OK)
|
||||
|
||||
NOTE: you must use the full format "0+1,512" for just he first
|
||||
block... no parameters can be implicit in this version.. THis is
|
||||
being fixed too.
|
||||
|
||||
* Linux ext2 filesystem works. (it's very slow for big files, but
|
||||
this is being fixed)
|
||||
|
||||
* Linux boot type now supported. Use a standard piggybacked image as
|
||||
with LILO. Put in hack to support >64MB via GRUB placing the RAM
|
||||
size as the first item on the command-line automatically. Must pass
|
||||
root partition on command-line using normal Linux syntax... if not,
|
||||
it uses it's builtin root partition.
|
||||
|
||||
* Supports chain-loading. For details, see "COMMANDS" and the
|
||||
examples directory. (was able to boot DOS and Windows NT on my test
|
||||
box). NOTE that the "root partition" must be set to work right.
|
||||
"makeactive" is currently a no-op.
|
||||
|
||||
* Several weird bugs fixed. One important note: If you recompile, it
|
||||
will warn about a clash with builtin "strcmp". This is normal...
|
||||
do NOT remove the strcmp definition, as then GCC will possibly put
|
||||
inline code from it's own builtin function in some places. (my
|
||||
strcmp has slightly different functionality, hence the problem)
|
||||
|
||||
* Mini-debugger is currently broken.
|
||||
|
||||
New in 0.2 - 1996-04-12, Erich Boleyn:
|
||||
|
||||
* Completely new menu-based UI. See "COMMANDS" and the examples
|
||||
directory for details. NOTE that the argument to a command must be
|
||||
preceded by a space between it and the '=', in both the config file
|
||||
and the command-line. This will be fixed.
|
||||
|
||||
New in 0.1 - 1996-03-31, Erich Boleyn:
|
||||
|
||||
* Newer version of Multiboot Standard (version 0.6) supported.
|
||||
|
||||
* Autodetects kernel types. Supports Multiboot, FreeBSD, NetBSD
|
||||
(Linux isn't finished).
|
||||
|
||||
* Stage 1.5 works now. Default setup is now for working with a BSD
|
||||
FFS floppy loading "/grub/stage2" as the main bootloader.
|
||||
|
||||
* Filesystem support improved. It didn't work on many floppies before
|
||||
(problem with the partition-detection code).
|
||||
|
||||
* Memory probe now supports arbitrary amounts of RAM (some technical
|
||||
limitations exist, see Multiboot standard version 0.6 for details).
|
||||
|
||||
* A mini-debugger is included by default, activated by hitting '~' on
|
||||
the command-line (it might interfere with things, but it seems OK
|
||||
for my alpha-testing). The commands are in the function

New in 0.0-19951210 - 1995-12-10, Erich Boleyn:
|

|
||||
* You can now perform TAB-based completion listing of any valid
|

partially completed disk/partition/file-name combination. Try it
|
||||
out to see what you like, examples are in the NOTES file under
|
||||
"Device completion".
|
||||
|

* Fixed a bug causing the memory size routine to sometimes report
|

ridiculous values.
|
||||
|
||||
* Fixed some documentation (what little there is :-/ and a few
|
||||
assembly bugs in the BIOS access routines that nobody reported yet,
|
||||
so I won't detail it here.

This is GNU GRUB, the GRand Unified Bootloader. GRUB is intended to
|
||||
provide important bootloader features that are missing from typical
|
||||
personal computer BIOSes:
|
||||
|
||||
- provides fully-featured command line and graphical interfaces
|
||||
- recognizes fdisk partitions and BSD disklabels
|
||||
- can dynamically read Linux ext2fs, ReiserFS, JFS and XFS, BSD ufs,
|
||||
MS-DOS FAT16 and FAT32, Minix fs, and VSTa fs filesystems, plus
|
||||
hardcoded blocklists
|
||||
- can boot Multiboot-compliant kernels (such as GNU Mach), as well
|
||||
as standard Linux and *BSD kernels
|
||||
|
||||
See the file NEWS for a description of recent changes to GRUB.
|
||||
|
||||
If you are interested in the network support, see the file
|
||||
README.netboot under the directory netboot.
|
||||
|
||||
See the file INSTALL for instructions on how to build and install the
|
||||
GRUB data and program files. See the GRUB manual for details about
|

using GRUB as your boot loader. Type "info grub" in the shell prompt.

Before working on anything in this file, it's very important that you
|
||||
make contact with the core GRUB developers. Things herein might be
|
||||
slightly out of date or otherwise not easy to understand at first
|
||||
glance. So write to <bug-grub@gnu.org> first.
|
||||
|
||||
Priorities:
|
||||
Reported bugs generally have top priority.
|
||||
Non-reported and non-encountered bugs (things we know don't work,
|
||||
but don't really impede things) have lower priority.
|
||||
Things in this file are ranked with one to three !; the more, the
|
||||
higher priority.
|
||||
|
||||
|
||||
Things that should be done before 1.0:
|
||||
|
||||
* Finish the Multiboot Speicification 0.7. !!!
|
||||
|
||||
* Add more --disable-FOO options to configure, so that you can create a
|
||||
minimum GRUB image. This is useful for boot floppies because of the size
|
||||
restriction. !
|
||||
|
||||
* Implement a new version of track_int13, using Virtual 8086 Mode. !!!
|
||||
|
||||
* Add missing features of graphics support. !!
|
||||
|
||||
Things that should _not_ be done before 1.0:
|
||||
|
||||
* Add configuration inclusion support by adding a command "include". !
|
||||
|
||||
* Add automatic configuration support.
|
||||
|
||||
* Add bunzip2 support.
|
||||
|
||||
* Define the module system.
|
||||
|
||||
* Add BSD syntax support, using results of ioprobe to map drives. !
|
||||
(0x1f0-0x1f7 = primary IDE, 0x170-0x176 = secondary,
|
||||
0x1e8-0x1ef = tertiary, 0x168-0x16f = quaternary).
|
||||
|
||||
* Add a real scripting language, possibly retaining backward
|
||||
compatibility so that old config files can be used.
|
||||
|
||||
* Add internationalization support, emulating gettext as much as is
|
||||
feasible.
|
||||
|
||||
* Support other architectures than i386-pc.
|
||||
|
||||
* Add real memory management.
|
||||
|
||||
|
||||
Things that may be done anytime:
|
||||
|
||||
* Port the script ``grub-install'' to OpenBSD. At least you will have to
|
||||
modify the function `convert' so that it can translate a native device
|
||||
name into the corresponding GRUB drive representation. !
|
||||
|
||||
* Add a command to run a GRUB script file. !!
|
||||
|
||||
* Add commands to manipulate the menu from the command-line interface. !
|
||||
|
||||
* Make symbolic links work for BSD FFS.
|
||||
|
||||
* Add indirect block support to the BSD FFS filesystem code, so files
|
||||
larger than 16MB can be read.
|
||||
|
||||
* Fix-up FreeBSD, NetBSD (and OpenBSD ?) command-line boot
|
||||
parameters.
|
||||
|
||||
* Support embedding a Stage 1.5 in the "bootloader" area of a FFS
|
||||
partition. (We already have the code, but need an approval by an
|
||||
expert before turning on the support. Any volunteers?)
|
||||
|
||||
* Support embedding a Stage 1.5 in the EXT2_BOOT_LOADER_INO of an ext2fs
|
||||
partition, so that it won't be accidentally erased or modified by
|
||||
the kernel.
|
||||
|
||||
* Add ISA PnP support.
|
||||
|
||||
* Add more filesystems support (NTFS, etc.)
|
||||
|
||||
* Add more remote console support (parallel and net).
|
||||
|
||||
* Add (real) RAID support.
|
||||
|
||||
? Add a partition naming syntax that means ``the first partition of
|
||||
this type''. We need this for clean Hurd install floppies.
|
||||
Nope. Improving the `find' command would solve this problem.
|
||||
|
||||
* Add CDROM-chainloading support. It would be enough to support only
|
||||
BIOSes which have bootable-CDROM support (so you may use the "Bootable
|
||||
CDROM" BIOS calls). It is not trivial to support BIOSes without the
|
||||
capability to boot CDROM.
|
||||
|
||||
? Divide pxegrub into two parts, so the initial image doesn't exceed
|
||||
the 32KB limit. I'm not sure if this is really necessary, because the
|
||||
PXE standard just says that it is _recommended_ to improve the
|
||||
modularity of a boot image. Obviously, this reason doesn't apply to
|
||||
GRUB, as pxegrub is merely a secondary boot loader. So whether this
|
||||
task should be done depends on if existing PXE ROMs support >32KB
|
||||
images or not, after all.

PREAMBLE
|
||||
|
||||
The purpose of this License is to make a manual, textbook, or other
|
||||
functional and useful document @dfn{free} in the sense of freedom: to
|
||||
assure everyone the effective freedom to copy and redistribute it,
|
||||
with or without modifying it, either commercially or noncommercially.
|
||||
Secondarily, this License preserves for the author and publisher a way
|
||||
to get credit for their work, while not being considered responsible
|
||||
for modifications made by others.
|
||||
|
||||
This License is a kind of ``copyleft'', which means that derivative
|
||||
works of the document must themselves be free in the same sense. It
|
||||
complements the GNU General Public License, which is a copyleft
|
||||
license designed for free software.
|
||||
|
||||
We have designed this License in order to use it for manuals for free
|
||||
software, because free software needs free documentation: a free
|
||||
program should come with manuals providing the same freedoms that the
|
||||
software does. But this License is not limited to software manuals;
|
||||
it can be used for any textual work, regardless of subject matter or
|
||||
whether it is published as a printed book. We recommend this License
|
||||
principally for works whose purpose is instruction or reference.
|
||||
|
||||
@item
|
||||
APPLICABILITY AND DEFINITIONS
|
||||
|
||||
This License applies to any manual or other work, in any medium, that
|
||||
contains a notice placed by the copyright holder saying it can be
|
||||
distributed under the terms of this License. Such a notice grants a
|
||||
world-wide, royalty-free license, unlimited in duration, to use that
|
||||
work under the conditions stated herein. The ``Document'', below,
|
||||
refers to any such manual or work. Any member of the public is a
|
||||
licensee, and is addressed as ``you''. You accept the license if you
|
||||
copy, modify or distribute the work in a way requiring permission
|
||||
under copyright law.
|
||||
|
||||
A ``Modified Version'' of the Document means any work containing the
|
||||
Document or a portion of it, either copied verbatim, or with
|
||||
modifications and/or translated into another language.
|
||||
|
||||
A ``Secondary Section'' is a named appendix or a front-matter section
|
||||
of the Document that deals exclusively with the relationship of the
|
||||
publishers or authors of the Document to the Document's overall
|
||||
subject (or to related matters) and contains nothing that could fall
|
||||
directly within that overall subject. (Thus, if the Document is in
|
||||
part a textbook of mathematics, a Secondary Section may not explain
|
||||
any mathematics.) The relationship could be a matter of historical
|
||||
connection with the subject or with related matters, or of legal,
|
||||
commercial, philosophical, ethical or political position regarding
|
||||
them.
|
||||
|
||||
The ``Invariant Sections'' are certain Secondary Sections whose titles
|
||||
are designated, as being those of Invariant Sections, in the notice
|
||||
that says that the Document is released under this License. If a
|
||||
section does not fit the above definition of Secondary then it is not
|
||||
allowed to be designated as Invariant. The Document may contain zero
|
||||
Invariant Sections. If the Document does not identify any Invariant
|
||||
Sections then there are none.
|
||||
|
||||
The ``Cover Texts'' are certain short passages of text that are listed,
|
||||
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
|
||||
the Document is released under this License. A Front-Cover Text may
|
||||
be at most 5 words, and a Back-Cover Text may be at most 25 words.
|
||||
|
||||
A ``Transparent'' copy of the Document means a machine-readable copy,
|
||||
represented in a format whose specification is available to the
|
||||
general public, that is suitable for revising the document
|
||||
straightforwardly with generic text editors or (for images composed of
|
||||
pixels) generic paint programs or (for drawings) some widely available
|
||||
drawing editor, and that is suitable for input to text formatters or
|
||||
for automatic translation to a variety of formats suitable for input
|
||||
to text formatters. A copy made in an otherwise Transparent file
|
||||
format whose markup, or absence of markup, has been arranged to thwart
|
||||
or discourage subsequent modification by readers is not Transparent.
|
||||
An image format is not Transparent if used for any substantial amount
|
||||
of text. A copy that is not ``Transparent'' is called ``Opaque''.
|
||||
|
||||
Examples of suitable formats for Transparent copies include plain
|
||||
@sc{ascii} without markup, Texinfo input format, La@TeX{} input
|
||||
format, @acronym{SGML} or @acronym{XML} using a publicly available
|
||||
@acronym{DTD}, and standard-conforming simple @acronym{HTML},
|
||||
PostScript or @acronym{PDF} designed for human modification. Examples
|
||||
of transparent image formats include @acronym{PNG}, @acronym{XCF} and
|
||||
@acronym{JPG}. Opaque formats include proprietary formats that can be
|
||||
read and edited only by proprietary word processors, @acronym{SGML} or
|
||||
@acronym{XML} for which the @acronym{DTD} and/or processing tools are
|
||||
not generally available, and the machine-generated @acronym{HTML},
|
||||
PostScript or @acronym{PDF} produced by some word processors for
|
||||
output purposes only.
|
||||
|
||||
The ``Title Page'' means, for a printed book, the title page itself,
|
||||
plus such following pages as are needed to hold, legibly, the material
|
||||
this License requires to appear in the title page. For works in
|
||||
formats which do not have any title page as such, ``Title Page'' means
|
||||
the text near the most prominent appearance of the work's title,
|
||||
preceding the beginning of the body of the text.
|
||||
|
||||
A section ``Entitled XYZ'' means a named subunit of the Document whose
|
||||
title either is precisely XYZ or contains XYZ in parentheses following
|
||||
text that translates XYZ in another language. (Here XYZ stands for a
|
||||
specific section name mentioned below, such as ``Acknowledgements'',
|
||||
``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
|
||||
of such a section when you modify the Document means that it remains a
|
||||
section ``Entitled XYZ'' according to this definition.
|
||||
|
||||
The Document may include Warranty Disclaimers next to the notice which
|
||||
states that this License applies to the Document. These Warranty
|
||||
Disclaimers are considered to be included by reference in this
|
||||
License, but only as regards disclaiming warranties: any other
|
||||
implication that these Warranty Disclaimers may have is void and has
|
||||
no effect on the meaning of this License.
|
||||
|
||||
@item
|
||||
VERBATIM COPYING
|
||||
|
||||
You may copy and distribute the Document in any medium, either
|
||||
commercially or noncommercially, provided that this License, the
|
||||
copyright notices, and the license notice saying this License applies
|
||||
to the Document are reproduced in all copies, and that you add no other
|
||||
conditions whatsoever to those of this License. You may not use
|
||||
technical measures to obstruct or control the reading or further
|
||||
copying of the copies you make or distribute. However, you may accept
|
||||
compensation in exchange for copies. If you distribute a large enough
|
||||
number of copies you must also follow the conditions in section 3.
|
||||
|
||||
You may also lend copies, under the same conditions stated above, and
|
||||
you may publicly display copies.
|
||||
|
||||
@item
|
||||
COPYING IN QUANTITY
|
||||
|
||||
If you publish printed copies (or copies in media that commonly have
|
||||
printed covers) of the Document, numbering more than 100, and the
|
||||
Document's license notice requires Cover Texts, you must enclose the
|
||||
copies in covers that carry, clearly and legibly, all these Cover
|
||||
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
|
||||
the back cover. Both covers must also clearly and legibly identify
|
||||
you as the publisher of these copies. The front cover must present
|
||||
the full title with all words of the title equally prominent and
|
||||
visible. You may add other material on the covers in addition.
|
||||
Copying with changes limited to the covers, as long as they preserve
|
||||
the title of the Document and satisfy these conditions, can be treated
|
||||
as verbatim copying in other respects.
|
||||
|
||||
If the required texts for either cover are too voluminous to fit
|
||||
legibly, you should put the first ones listed (as many as fit
|
||||
reasonably) on the actual cover, and continue the rest onto adjacent
|
||||
pages.
|
||||
|
||||
If you publish or distribute Opaque copies of the Document numbering
|
||||
more than 100, you must either include a machine-readable Transparent
|
||||
copy along with each Opaque copy, or state in or with each Opaque copy
|
||||
a computer-network location from which the general network-using
|
||||
public has access to download using public-standard network protocols
|
||||
a complete Transparent copy of the Document, free of added material.
|
||||
If you use the latter option, you must take reasonably prudent steps,
|
||||
when you begin distribution of Opaque copies in quantity, to ensure
|
||||
that this Transparent copy will remain thus accessible at the stated
|
||||
location until at least one year after the last time you distribute an
|
||||
Opaque copy (directly or through your agents or retailers) of that
|
||||
edition to the public.
|
||||
|
||||
It is requested, but not required, that you contact the authors of the
|
||||
Document well before redistributing any large number of copies, to give
|
||||
them a chance to provide you with an updated version of the Document.
|
||||
|
||||
@item
|
||||
MODIFICATIONS
|
||||
|
||||
You may copy and distribute a Modified Version of the Document under
|
||||
the conditions of sections 2 and 3 above, provided that you release
|
||||
the Modified Version under precisely this License, with the Modified
|
||||
Version filling the role of the Document, thus licensing distribution
|
||||
and modification of the Modified Version to whoever possesses a copy
|
||||
of it. In addition, you must do these things in the Modified Version:
|
||||
|
||||
@enumerate A
|
||||
@item
|
||||
Use in the Title Page (and on the covers, if any) a title distinct
|
||||
from that of the Document, and from those of previous versions
|
||||
(which should, if there were any, be listed in the History section
|
||||
of the Document). You may use the same title as a previous version
|
||||
if the original publisher of that version gives permission.
|
||||
|
||||
@item
|
||||
List on the Title Page, as authors, one or more persons or entities
|
||||
responsible for authorship of the modifications in the Modified
|
||||
Version, together with at least five of the principal authors of the
|
||||
Document (all of its principal authors, if it has fewer than five),
|
||||
unless they release you from this requirement.
|
||||
|
||||
@item
|
||||
State on the Title page the name of the publisher of the
|
||||
Modified Version, as the publisher.
|
||||
|
||||
@item
|
||||
Preserve all the copyright notices of the Document.
|
||||
|
||||
@item
|
||||
Add an appropriate copyright notice for your modifications
|
||||
adjacent to the other copyright notices.
|
||||
|
||||
@item
|
||||
Include, immediately after the copyright notices, a license notice
|
||||
giving the public permission to use the Modified Version under the
|
||||
terms of this License, in the form shown in the Addendum below.
|
||||
|
||||
@item
|
||||
Preserve in that license notice the full lists of Invariant Sections
|
||||
and required Cover Texts given in the Document's license notice.
|
||||
|
||||
@item
|
||||
Include an unaltered copy of this License.
|
||||
|
||||
@item
|
||||
Preserve the section Entitled ``History'', Preserve its Title, and add
|
||||
to it an item stating at least the title, year, new authors, and
|
||||
publisher of the Modified Version as given on the Title Page. If
|
||||
there is no section Entitled ``History'' in the Document, create one
|
||||
stating the title, year, authors, and publisher of the Document as
|
||||
given on its Title Page, then add an item describing the Modified
|
||||
Version as stated in the previous sentence.
|
||||
|
||||
@item
|
||||
Preserve the network location, if any, given in the Document for
|
||||
public access to a Transparent copy of the Document, and likewise
|
||||
the network locations given in the Document for previous versions
|
||||
it was based on. These may be placed in the ``History'' section.
|
||||
You may omit a network location for a work that was published at
|
||||
least four years before the Document itself, or if the original

the Title of the section, and preserve in the section all the

substance and tone of each of the contributor acknowledgements and/or

dedications given therein.
|

|

@item
|

Preserve all the Invariant Sections of the Document,

unaltered in their text and in their titles. Section numbers
|

or the equivalent are not considered part of the section titles.
|
||||
|
||||
@item
|
||||
Delete any section Entitled ``Endorsements''. Such a section
|
||||
may not be included in the Modified Version.
|
||||
|
||||
@item
|

Do not retitle any existing section to be Entitled ``Endorsements'' or

Preserve any Warranty Disclaimers.

@end enumerate
|

|

If the Modified Version includes new front-matter sections or
|
||||
appendices that qualify as Secondary Sections and contain no material
|
||||
copied from the Document, you may at your option designate some or all
|
||||
of these sections as invariant. To do this, add their titles to the
|
||||
list of Invariant Sections in the Modified Version's license notice.
|
||||
These titles must be distinct from any other section titles.
|
||||
|
||||
You may add a section Entitled ``Endorsements'', provided it contains
|
||||
nothing but endorsements of your Modified Version by various
|
||||
parties---for example, statements of peer review or that the text has
|
||||
been approved by an organization as the authoritative definition of a
|
||||
standard.
|
||||
|
||||
You may add a passage of up to five words as a Front-Cover Text, and a
|
||||
passage of up to 25 words as a Back-Cover Text, to the end of the list
|
||||
of Cover Texts in the Modified Version. Only one passage of
|
||||
Front-Cover Text and one of Back-Cover Text may be added by (or
|
||||
through arrangements made by) any one entity. If the Document already
|
||||
includes a cover text for the same cover, previously added by you or
|
||||
by arrangement made by the same entity you are acting on behalf of,
|
||||
you may not add another; but you may replace the old one, on explicit
|
||||
permission from the previous publisher that added the old one.
|
||||
|
||||
The author(s) and publisher(s) of the Document do not by this License
|
||||
give permission to use their names for publicity for or to assert or
|
||||
imply endorsement of any Modified Version.
|
||||
|
||||
@item
|
||||
COMBINING DOCUMENTS
|
||||
|
||||
You may combine the Document with other documents released under this
|
||||
License, under the terms defined in section 4 above for modified
|
||||
versions, provided that you include in the combination all of the
|
||||
Invariant Sections of all of the original documents, unmodified, and
|
||||
list them all as Invariant Sections of your combined work in its
|
||||
license notice, and that you preserve all their Warranty Disclaimers.
|
||||
|
||||
The combined work need only contain one copy of this License, and
|
||||
multiple identical Invariant Sections may be replaced with a single
|
||||
copy. If there are multiple Invariant Sections with the same name but
|
||||
different contents, make the title of each such section unique by
|
||||
adding at the end of it, in parentheses, the name of the original
|
||||
author or publisher of that section if known, or else a unique number.
|
||||
Make the same adjustment to the section titles in the list of
|
||||
Invariant Sections in the license notice of the combined work.
|
||||
|
||||
In the combination, you must combine any sections Entitled ``History''
|
||||
in the various original documents, forming one section Entitled
|
||||
``History''; likewise combine any sections Entitled ``Acknowledgements'',
|
||||
and any sections Entitled ``Dedications''. You must delete all
|
||||
sections Entitled ``Endorsements.''
|
||||
|
||||
@item
|
||||
COLLECTIONS OF DOCUMENTS
|
||||
|
||||
You may make a collection consisting of the Document and other documents
|
||||
released under this License, and replace the individual copies of this
|
||||
License in the various documents with a single copy that is included in
|
||||
the collection, provided that you follow the rules of this License for
|
||||
verbatim copying of each of the documents in all other respects.
|
||||
|
||||
You may extract a single document from such a collection, and distribute
|
||||
it individually under this License, provided you insert a copy of this
|
||||
License into the extracted document, and follow this License in all
|
||||
other respects regarding verbatim copying of that document.
|
||||
|
||||
@item
|
||||
AGGREGATION WITH INDEPENDENT WORKS
|
||||
|
||||
A compilation of the Document or its derivatives with other separate
|
||||
and independent documents or works, in or on a volume of a storage or
|
||||
distribution medium, is called an ``aggregate'' if the copyright
|
||||
resulting from the compilation is not used to limit the legal rights
|
||||
of the compilation's users beyond what the individual works permit.
|
||||
When the Document is included in an aggregate, this License does not
|
||||
apply to the other works in the aggregate which are not themselves
|
||||
derivative works of the Document.
|
||||
|
||||
If the Cover Text requirement of section 3 is applicable to these
|
||||
copies of the Document, then if the Document is less than one half of
|
||||
the entire aggregate, the Document's Cover Texts may be placed on
|
||||
covers that bracket the Document within the aggregate, or the
|
||||
electronic equivalent of covers if the Document is in electronic form.
|
||||
Otherwise they must appear on printed covers that bracket the whole
|
||||
aggregate.
|
||||
|
||||
@item
|
||||
TRANSLATION
|
||||
|
||||
Translation is considered a kind of modification, so you may
|
||||
distribute translations of the Document under the terms of section 4.
|
||||
Replacing Invariant Sections with translations requires special
|
||||
permission from their copyright holders, but you may include
|
||||
translations of some or all Invariant Sections in addition to the
|
||||
original versions of these Invariant Sections. You may include a
|
||||
translation of this License, and all the license notices in the
|
||||
Document, and any Warranty Disclaimers, provided that you also include
|
||||
the original English version of this License and the original versions
|
||||
of those notices and disclaimers. In case of a disagreement between
|
||||
the translation and the original version of this License or a notice
|
||||
or disclaimer, the original version will prevail.
|
||||
|
||||
If a section in the Document is Entitled ``Acknowledgements'',
|
||||
``Dedications'', or ``History'', the requirement (section 4) to Preserve
|
||||
its Title (section 1) will typically require changing the actual
|
||||
title.
|
||||
|
||||
@item
|
||||
TERMINATION
|
||||
|
||||
You may not copy, modify, sublicense, or distribute the Document except
|
||||
as expressly provided for under this License. Any other attempt to
|
||||
copy, modify, sublicense or distribute the Document is void, and will
|
||||
automatically terminate your rights under this License. However,
|
||||
parties who have received copies, or rights, from you under this
|
||||
License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||

|
||||
FUTURE REVISIONS OF THIS LICENSE
|
||||
|
||||
The Free Software Foundation may publish new, revised versions
|
||||
of the GNU Free Documentation License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns. See
|
||||
@uref{http://www.gnu.org/copyleft/}.
|
||||
|
||||
Each version of the License is given a distinguishing version number.
|
||||
If the Document specifies that a particular numbered version of this
|
||||
License ``or any later version'' applies to it, you have the option of
|
||||
following the terms and conditions either of that specified version or
|
||||
of any later version that has been published (not as a draft) by the
|
||||
Free Software Foundation. If the Document does not specify a version
|
||||
number of this License, you may choose any version ever published (not
|
||||
as a draft) by the Free Software Foundation.

|
||||
|
||||
To use this License in a document you have written, include a copy of
|
||||
the License in the document and put the following copyright and
|
||||
license notices just after the title page:
|
||||
|
||||
@smallexample
|
||||
@group
|
||||
Copyright (C) @var{year} @var{your name}.
|
||||
Permission is granted to copy, distribute and/or modify this document
|
||||
under the terms of the GNU Free Documentation License, Version 1.2
|
||||
or any later version published by the Free Software Foundation;
|
||||
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
|
||||
Texts. A copy of the license is included in the section entitled ``GNU
|
||||
Free Documentation License''.
|
||||
@end group
|
||||
@end smallexample
|
||||
|
||||
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
|
||||
replace the ``with...Texts.'' line with this:
|
||||
|
||||
@smallexample
|
||||
@group
|
||||
with the Invariant Sections being @var{list their titles}, with
|
||||
the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
|
||||
being @var{list}.
|
||||
@end group
|
||||
@end smallexample
|
||||
|
||||
If you have Invariant Sections without Cover Texts, or some other
|
||||
combination of the three, merge those two alternatives to suit the
|
||||
situation.
|
||||
|
||||
If your document contains nontrivial examples of program code, we
|
||||
recommend releasing these examples in parallel under your choice of
|
||||
free software license, such as the GNU General Public License,
|
||||
to permit their use in free software.

@section The memory map of various components
|
||||
|
||||
GRUB consists of two distinct components, called @dfn{stages}, which are
|
||||
loaded at different times in the boot process. Because they run
|
||||
mutual-exclusively, sometimes a memory area overlaps with another
|
||||
memory area. And, even in one stage, a single memory area can be used
|
||||
for various purposes, because their usages are mutually exclusive.
|
||||
|
||||
Here is the memory map of the various components:
|
||||
|
||||
@table @asis
|
||||
@item 0 to 4K-1
|
||||
BIOS and real mode interrupts
|
||||
|
||||
@item 0x07BE to 0x07FF
|
||||
Partition table passed to another boot loader
|
||||
|
||||
@item down from 8K-1
|
||||
Real mode stack
|
||||
|
||||
@item 0x2000 to ?
|
||||
The optional Stage 1.5 is loaded here
|
||||
|
||||
@item 0x2000 to 0x7FFF
|
||||
Command-line buffer for Multiboot kernels and modules
|
||||
|
||||
@item 0x7C00 to 0x7DFF
|
||||
Stage 1 is loaded here by BIOS or another boot loader
|
||||
|
||||
@item 0x7F00 to 0x7F42
|
||||
LBA drive parameters
|
||||
|
||||
@item 0x8000 to ?
|
||||
Stage2 is loaded here
|
||||
|
||||
@item The end of Stage 2 to 416K-1
|
||||
Heap, in particular used for the menu
|
||||
|
||||
@item down from 416K-1
|
||||
Protected mode stack
|
||||
|
||||
@item 416K to 448K-1
|
||||
Filesystem buffer
|
||||
|
||||
@item 448K to 479.5K-1
|
||||
Raw device buffer
|
||||
|
||||
@item 479.5K to 480K-1
|
||||
512-byte scratch area
|
||||
|
||||
@item 480K to 512K-1
|
||||
Buffers for various functions, such as password, command-line, cut and
|
||||
paste, and completion.
|
||||
|
||||
@item The last 1K of lower memory
|
||||
Disk swapping code and data
|

||||
well-defined, so that the installation can patch the binary file
|
||||
directly without recompilation of the stages.
|
||||
|
||||
In Stage 1, these are defined:
|
||||
|
||||
@table @code
|
||||
@item 0x3E
|
||||
The version number (not GRUB's, but the installation mechanism's).
|
||||
|
||||
@item 0x40
|
||||
The boot drive. If it is 0xFF, use a drive passed by BIOS.
|
||||
|
||||
@item 0x41
|
||||
The flag for if forcing LBA.
|
||||
|
||||
@item 0x42
|
||||
The starting address of Stage 2.
|
||||
|
||||
@item 0x44
|
||||
The first sector of Stage 2.
|
||||
|
||||
@item 0x48
|
||||
The starting segment of Stage 2.
|
||||
|
||||
@item 0x1FE
|
||||
The signature (@code{0xAA55}).
|
||||
@end table
|
||||
|
||||
See the file @file{stage1/stage1.S}, for more information.
|
||||
|
||||
In the first sector of Stage 1.5 and Stage 2, the blocklists are
|
||||
recorded between @code{firstlist} and @code{lastlist}. The address of
|
||||
@code{lastlist} is determined when assembling the file
|
||||
@file{stage2/start.S}.
|
||||
|
||||
The trick here is that it is actually read backward, and the first
|
||||
8-byte blocklist is not read here, but after the pointer is decremented
|
||||
8 bytes, then after reading it, it decrements again, reads, and so on,
|
||||
until it is finished. The terminating condition is when the number of
|
||||
sectors to be read in the next blocklist is zero.
|
||||
|
||||
The format of a blocklist can be seen from the example in the code just
|
||||
before the @code{firstlist} label. Note that it is always from the
|
||||
beginning of the disk, but @emph{not} relative to the partition
|
||||
boundaries.
|
||||
|
||||
In the second sector of Stage 1.5 and Stage 2, these are defined:
|
||||
|
||||
@table @asis
|
||||
@item @code{0x6}
|
||||
The version number (likewise, the installation mechanism's).
|
||||
|
||||
@item @code{0x8}
|
||||
The installed partition.
|
||||
|
||||
@item @code{0xC}
|
||||
The saved entry number.
|
||||
|
||||
@item @code{0x10}
|
||||
The identifier.
|
||||
|
||||
@item @code{0x11}
|
||||
The flag for if forcing LBA.
|
||||
|
||||
@item @code{0x12}
|
||||
The version string (GRUB's).
|
||||
|
||||
@item @code{0x12} + @dfn{the length of the version string}
|
||||
The name of a configuration file.
|
||||
@end table
|
||||
|
||||
See the file @file{stage2/asm.S}, for more information.
|
||||
|
||||
|
||||
@node Filesystem interface
|
||||
@section The generic interface for filesystems
|
||||
|
||||
For any particular partition, it is presumed that only one of the
|
||||
@dfn{normal} filesystems such as FAT, FFS, or ext2fs can be used, so
|
||||
there is a switch table managed by the functions in
|
||||
@file{disk_io.c}. The notation is that you can only @dfn{mount} one at a
|
||||
time.
|
||||
|
||||
The blocklist filesystem has a special place in the system. In addition
|
||||
to the @dfn{normal} filesystem (or even without one mounted), you can
|
||||
access disk blocks directly (in the indicated partition) via the block
|
||||
list notation. Using the blocklist filesystem doesn't effect any other
|
||||
filesystem mounts.
|
||||
|
||||
The variables which can be read by the filesystem backend are:
|
||||
|
||||
@vtable @code
|
||||
@item current_drive
|
||||
The current BIOS drive number (numbered from 0, if a floppy, and
|
||||
numbered from 0x80, if a hard disk).
|
||||
|
||||
@item current_partition
|
||||
The current partition number.
|
||||
|
||||
@item current_slice
|
||||
The current partition type.
|
||||
|
||||
@item saved_drive
|
||||
The @dfn{drive} part of the root device.
|
||||
|
||||
@item saved_partition
|
||||
The @dfn{partition} part of the root device.
|
||||
|
||||
@item part_start
|
||||
The current partition starting address, in sectors.
|
||||
|
||||
@item part_length
|
||||
The current partition length, in sectors.
|
||||
|
||||
@item print_possibilities
|
||||
True when the @code{dir} function should print the possible completions
|
||||
of a file, and false when it should try to actually open a file of that
|
||||
name.
|
||||
|
||||
@item FSYS_BUF
|
||||
Filesystem buffer which is 32K in size, to use in any way which the
|
||||
filesystem backend desires.
|
||||
@end vtable
|
||||
|
||||
The variables which need to be written by a filesystem backend are:
|
||||
|
||||
@vtable @code
|
||||
@item filepos
|
||||
The current position in the file, in sectors.
|
||||
|
||||
@strong{Caution:} the value of @var{filepos} can be changed out from
|
||||
under the filesystem code in the current implementation. Don't depend on
|
||||
it being the same for later calls into the backend code!
|
||||
|
||||
@item filemax
|
||||
The length of the file.
|
||||
|
||||
@item disk_read_func
|
||||
The value of @var{disk_read_hook} @emph{only} during reading of data
|
||||
for the file, not any other fs data, inodes, FAT tables, whatever, then
|
||||
set to @code{NULL} at all other times (it will be @code{NULL} by
|
||||
default). If this isn't done correctly, then the @command{testload} and
|
||||
@command{install} commands won't work correctly.
|
||||
@end vtable
|
||||
|
||||
The functions expected to be used by the filesystem backend are:
|
||||
|
||||
@ftable @code
|
||||
@item devread
|
||||
Only read sectors from within a partition. Sector 0 is the first sector
|
||||
in the partition.
|
||||
|
||||
@item grub_read
|
||||
If the backend uses the blocklist code, then @code{grub_read} can be
|
||||
used, after setting @var{block_file} to 1.
|
||||
|
||||
@item print_a_completion
|
||||
If @var{print_possibilities} is true, call @code{print_a_completion} for
|
||||
each possible file name. Otherwise, the file name completion won't work.
|
||||
@end ftable
|
||||
|
||||
The functions expected to be defined by the filesystem backend are
|
||||
described at least moderately in the file @file{filesys.h}. Their usage
|
||||
is fairly evident from their use in the functions in @file{disk_io.c},
|
||||
look for the use of the @var{fsys_table} array.
|
||||
|
||||
@strong{Caution:} The semantics are such that then @samp{mount}ing the
|
||||
filesystem, presume the filesystem buffer @code{FSYS_BUF} is corrupted,
|
||||
and (re-)load all important contents. When opening and reading a file,
|
||||
presume that the data from the @samp{mount} is available, and doesn't
|
||||
get corrupted by the open/read (i.e. multiple opens and/or reads will be
|
||||
done with only one mount if in the same filesystem).
|
||||
|
||||
|
||||
@node Command interface
|
||||
@section The generic interface for built-ins
|
||||
|
||||
GRUB built-in commands are defined in a uniform interface, whether
|
||||
they are menu-specific or can be used anywhere. The definition of a
|
||||
built-in command consists of two parts: the code itself and the table of
|
||||
the information.
|
||||
|
||||
The code must be a function which takes two arguments, a command-line
|
||||
string and flags, and returns an @samp{int} value. The @dfn{flags}
|
||||
argument specifies how the function is called, using a bit mask. The
|
||||
return value must be zero if successful, otherwise non-zero. So it is
|
||||
normally enough to return @var{errnum}.
|
||||
|
||||
The table of the information is represented by the structure
|
||||
@code{struct builtin}, which contains the name of the command, a pointer
|
||||
to the function, flags, a short description of the command and a long
|
||||
description of the command. Since the descriptions are used only for
|
||||
help messages interactively, you don't have to define them, if the
|
||||
command may not be called interactively (such as @command{title}).
|
||||
|
||||
The table is finally registered in the table @var{builtin_table}, so
|
||||
that @code{run_script} and @code{enter_cmdline} can find the
|
||||
command. See the files @file{cmdline.c} and @file{builtins.c}, for more
|
||||
details.
|
||||
|
||||
|
||||
@node Bootstrap tricks
|
||||
@section The bootstrap mechanism used in GRUB
|
||||
|
||||
The disk space can be used in a boot loader is very restricted because
|
||||
a MBR (@pxref{MBR}) is only 512 bytes but it also contains a partition
|
||||
table (@pxref{Partition table}) and a BPB. So the question is how to
|
||||
make a boot loader code enough small to be fit in a MBR.
|
||||
|
||||
However, GRUB is a very large program, so we break GRUB into 2 (or 3)
|
||||
distinct components, @dfn{Stage 1} and @dfn{Stage 2} (and optionally
|
||||
@dfn{Stage 1.5}). @xref{Memory map}, for more information.
|
||||
|
||||
We embed Stage 1 in a MBR or in the boot sector of a partition, and
|
||||
place Stage 2 in a filesystem. The optional Stage 1.5 can be installed
|
||||
in a filesystem, in the @dfn{boot loader} area in a FFS or a ReiserFS,
|
||||
and in the sectors right after a MBR, because Stage 1.5 is enough small
|
||||
and the sectors right after a MBR is normally an unused region. The size
|
||||
of this region is the number of sectors per head minus 1.
|
||||
|
||||
Thus, all Stage1 must do is just load Stage2 or Stage1.5. But even if
|
||||
Stage 1 needs not to support the user interface or the filesystem
|
||||
interface, it is impossible to make Stage 1 less than 400 bytes, because
|
||||
GRUB should support both the CHS mode and the LBA mode (@pxref{Low-level
|
||||
disk I/O}).
|
||||
|
||||
The solution used by GRUB is that Stage 1 loads only the first sector of
|
||||
Stage 2 (or Stage 1.5) and Stage 2 itself loads the rest. The flow of
|
||||
Stage 1 is:
|
||||
|
||||
@enumerate
|
||||
@item
|
||||
Initialize the system briefly.
|
||||
|
||||
@item
|
||||
Detect the geometry and the accessing mode of the @dfn{loading drive}.
|
||||
|
||||
@item
|
||||
Load the first sector of Stage 2.
|
||||
|
||||
@item
|
||||
Jump to the starting address of the Stage 2.
|
||||
@end enumerate
|
||||
|
||||
The flow of Stage 2 (and Stage 1.5) is:
|
||||
|
||||
@enumerate
|
||||
@item
|
||||
Load the rest of itself to the real starting address, that is, the
|
||||
starting address plus 512 bytes. The blocklists are stored in the last
|
||||
part of the first sector.
|
||||
|
||||
@item
|
||||
Long jump to the real starting address.
|
||||
@end enumerate
|
||||
|
||||
Note that Stage 2 (or Stage 1.5) does not probe the geometry
|
||||
or the accessing mode of the @dfn{loading drive}, since Stage 1 has
|
||||
already probed them.

@node Submitting patches
|

@section Where and how you should send patches
|
||||
|
||||
When you write patches for GRUB, please send them to the mailing list
|
||||
@email{bug-grub@@gnu.org}. Here is the list of items of which you
|
||||
should take care:
|
||||
|
||||
@itemize @bullet
|
||||
@item
|
||||
Please make your patch as small as possible. Generally, it is not a good
|
||||
thing to make one big patch which changes many things. Instead,
|
||||
segregate features and produce many patches.
|
||||
|
||||
@item
|
||||
Use as late code as possible, for the original code. The CVS repository
|
||||
always has the current version (@pxref{Obtaining and Building GRUB}).
|
||||
|
||||
@item
|
||||
Write ChangeLog entries. @xref{Change Logs, , Change Logs, standards,
|
||||
GNU Coding Standards}, if you don't know how to write ChangeLog.
|
||||
|
||||
@item
|
||||
Make patches in unified diff format. @samp{diff -urN} is appropriate in
|
||||
most cases.
|
||||
|
||||
@item
|
||||
Don't make patches reversely. Reverse patches are difficult to read and
|
||||
use.
|
||||
|
||||
@item
|
||||
Be careful enough of the license term and the copyright. Because GRUB
|
||||
is under GNU General Public License, you may not steal code from
|
||||
software whose license is incompatible against GPL. And, if you copy
|
||||
code written by others, you must not ignore their copyrights. Feel free
|
||||
to ask GRUB maintainers, whenever you are not sure what you should do.
|
||||
|
||||
@item
|
||||
If your patch is too large to send in e-mail, put it at somewhere we can
|
||||
see. Usually, you shouldn't send e-mail over 20K.

I OVERVIEW
|
||||
|
||||
The 3c90X series ethernet cards are a group of high-performance busmaster
|
||||
DMA cards from 3Com. This particular driver supports both the 3c90x and
|
||||
the 3c90xB revision cards. 3C90xC family support has been tested to some
|
||||
degree but not extensively.
|
||||

||||

documentation "3c90x.txt" before compiling and using this driver.
|
||||
|
||||
|
||||
II FLASH PROMS
|
||||
|
||||
The 3c90xB cards, according to the 3Com documentation, only accept the
|
||||
following flash memory chips:
|
||||
|
||||
Atmel AT29C512 (64 kilobyte)
|
||||
Atmel AT29C010 (128 kilobyte)
|
||||
|
||||
The 3c90x cards, according to the 3Com documentation, accept the
|
||||
following flash memory chips capacities:
|
||||
|
||||
64 kb (8 kB)
|
||||
128 kb (16 kB)
|
||||
256 kb (32 kB) and
|
||||
512 kb (64 kB)
|
||||
|
||||
Atmel AT29C512 (64 kilobyte) chips are specifically listed for both
|
||||
adapters, but flashing on the 3c905b cards would only be supported
|
||||
through the Atmel parts. Any device, of the supported size, should
|
||||
be supported when programmed by a dedicated PROM programmer (e.g.
|
||||
not the card).
|
||||
|
||||
To use this driver in such a PROM, visit Atmel's web site and download
|
||||
their .PDF file containing a list of their distributors. Contact the
|
||||
distributors for pricing information. The prices are quite reasonable
|
||||
(about $3 US each for the 64 kB part), and are comparable to what one would
|
||||
expect for similarly sized standard EPROMs. And, the flash chips are much
|
||||
easier to work with, as they don't need to be UV-erased to be reprogrammed.
|
||||
The 3C905B card actually provides a method to program the flash memory
|
||||
while it is resident on board the card itself; if someone would like to
|
||||
write a small DOS program to do the programming, I can provide the
|
||||
information about the registers and so forth.
|
||||
|
||||
A utility program, 3c90xutil, is provided with Etherboot in the 'contrib'
|
||||
directory that allows for the on-board flashing of the ROM while Linux
|
||||
is running. The program has been successfully used under Linux, but I
|
||||
have heard problem reports of its use under FreeBSD. Anyone willing to
|
||||
make it work under FreeBSD is more than welcome to do so!
|
||||
|
||||
You also have the option of using EPROM chips - the 3C905B-TX-NM has been
|
||||
successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a
|
||||
specified access time of 100ns and faster.
|
||||
|
||||
|
||||
III GENERAL USE
|
||||
|
||||
Normally, the basic procedure for using this driver is as follows:
|
||||
|
||||
1. Run the 3c90xcfg program on the driver diskette to enable the
|
||||
boot PROM and set it to 64k or 128k, as appropriate.
|
||||
2. Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with
|
||||
possibly the value CFG_3C90X_XCVR defined to the transceiver type that
|
||||
you want to use (i.e., 10/100 rj45, AUI, coax, MII).
|
||||
3. Run the floppy image on the PC to be network booted, to get
|
||||
it configured, and to verify that it will boot properly.
|
||||
4. Build the 3c90x.rom or 3c90x.lzrom PROM image and program
|
||||
it into the flash or EPROM memory chip.
|
||||
5. Put the PROM in the ethernet card, boot and enable 'boot from
|
||||
network first' in the system BIOS, save and reboot.
|
||||
|
||||
Here are some issues to be aware of:
|
||||
|
||||
1. If you experience crashes or different behaviour when using the
|
||||
boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the
|
||||
steps 2-5 above. This works around a bug in some 3c905B cards (see
|
||||
below), but has some side-effects which may not be desirable.
|
||||
Please note that you have to boot off a floppy (not PROM!) once for
|
||||
this fix to take effect.
|
||||
2. The possible need to manually set the CFG_3C90X_XCVR value to
|
||||
configure the transceiver type. Values are listed below.
|
||||
3. The possible need to define CFG_3C90X_PRESERVE_XCVR for use in
|
||||
operating systems that don't intelligently determine the
|
||||
transceiver type.
|
||||
|
||||
Some things that are on the 'To-Do' list, perhaps for me, but perhaps
|
||||
for any other volunteers out there:
|
||||
|
||||
1. Extend the driver to fully implement the auto-select
|
||||
algorithm if the card has multiple media ports.
|
||||
2. Fix any bugs in the code <grin>....
|
||||
3. Extend the driver to support the 3c905c revision cards
|
||||
"officially". Right now, the support has been primarily empirical
|
||||
and not based on 3c905C documentation.
|
||||
|
||||
Now for the details....
|
||||
|
||||
This driver has been tested on roughly 300 systems. The main two
|
||||
configuration issues to contend with are:
|
||||
|
||||
1. Ensure that PCI Busmastering is enabled for the adapter (configured
|
||||
in the CMOS setup)
|
||||
2. Some systems don't work properly with the adapter when plug and
|
||||
play OS is enabled; I always set it to "No" or "Disabled" -- this makes
|
||||
it easier and really doesn't adversely affect anything.
|
||||
|
||||
Roughly 95% of the systems worked when configured properly. A few
|
||||
have issues with booting locally once the boot PROM has been installed
|
||||
(this number has been less than 2%). Other configuration issues that
|
||||
to check:
|
||||
|
||||
1. Newer BIOS's actually work correctly with the network boot order.
|
||||
Set the network adapter first. Most older BIOS's automatically go to
|
||||
the network boot PROM first.
|
||||
2. For systems where the adapter was already installed and is just
|
||||
having the PROM installed, try setting the "reset configuration data"
|
||||
to yes in the CMOS setup if the BIOS isn't seen at first. If your BIOS
|
||||
doesn't have this option, remove the card, start the system, shut down,
|
||||
install the card and restart (or switch to a different PCI slot).
|
||||
3. Make sure the CMOS security settings aren't preventing a boot.
|
||||
|
||||
The 3c905B cards have a significant 'bug' that relates to the flash prom:
|
||||
unless the card is set internally to the MII transceiver, it will only
|
||||
read the first 8k of the PROM image. Don't ask why -- it seems really
|
||||
obscure, but it has to do with the way they mux'd the address lines
|
||||
from the PCI bus to the ROM. Unfortunately, most of us are not using
|
||||
MII transceivers, and even the .lzrom image ends up being just a little
|
||||
bit larger than 8k. Note that the workaround for this is disabled by
|
||||
default, because the Windows NT 4.0 driver does not like it (no packets
|
||||
are transmitted).
|
||||
|
||||
So, the solution that I've used is to internally set the card's nvram
|
||||
configuration to use MII when it boots. The 3c905b driver does this
|
||||
automatically. This way, the 16k prom image can be loaded into memory,
|
||||
and then the 3c905b driver can set the temporary configuration of the
|
||||
card to an appropriate value, either configurable by the user or chosen
|
||||
by the driver.
|
||||
|
||||
To enable the 3c905B bugfix, which is necessary for these cards when
|
||||
booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building,
|
||||
create a floppy image and boot it once.
|
||||
Thereafter, the card should accept the larger prom image.
|
||||
|
||||
The driver should choose an appropriate transceiver on the card. However,
|
||||
if it doesn't on your card or if you need to, for instance, set your
|
||||
card to 10mbps when connected to an unmanaged 10/100 hub, you can specify
|
||||
which transceiver you want to use. To do this, build the 3c905b.fd0
|
||||
image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following
|
||||
values:
|
||||
|
||||
0 10Base-T
|
||||
1 10mbps AUI
|
||||
3 10Base-2 (thinnet/coax)
|
||||
4 100Base-TX
|
||||
5 100Base-FX
|
||||
6 MII
|
||||
8 Auto-negotiation 10Base-T / 100Base-TX (usually the default)
|
||||
9 MII External MAC Mode
|
||||
255 Allow driver to choose an 'appropriate' media port.
|
||||
|
||||
Then proceed from step 2 in the above 'general use' instructions. The
|
||||
.rom image can be built with CFG_3C90X_XCVR set to a value, but you
|
||||
normally don't want to do this, since it is easier to change the
|
||||
transceiver type by rebuilding a new floppy, changing the BIOS to floppy
|
||||
boot, booting, and then changing the BIOS back to network boot. If
|
||||
CFG_3C90X_XCVR is not set in a particular build, it just uses the
|
||||
current configuration (either its 'best guess' or whatever the stored
|
||||
CFG_3C90X_XCVR value was from the last time it was set).
|
||||
|
||||
[[ Note for the more technically inclined: The CFG_3C90X_XCVR value is
|
||||
programmed into a register in the card's NVRAM that was reserved for
|
||||
LanWorks PROM images to use. When the driver boots, the card comes
|
||||
up in MII mode, and the driver checks the LanWorks register to find
|
||||
out if the user specified a transceiver type. If it finds that
|
||||
information, it uses that, otherwise it picks a transceiver that the
|
||||
card has based on the 3c905b's MediaOptions register. This driver isn't
|
||||
quite smart enough to always determine which media port is actually
|
||||
_connected_; maybe someone else would like to take on that task (it
|
||||
actually involves sending a self-directed packet and seeing if it
|
||||
comes back. IF it does, that port is connected). ]]
|
||||
|
||||
Another issue to keep in mind is that it is possible that some OS'es
|
||||
might not be happy with the way I've handled the PROM-image hack with
|
||||
setting MII mode on bootup. Linux 2.0.35 does not have this problem.
|
||||
Behavior of other systems may vary. The 3com documentation specifically
|
||||
says that, at least with the card that I have, the device driver in the
|
||||
OS should auto-select the media port, so other drivers should work fine
|
||||
with this 'hack'. However, if yours doesn't seem to, you can try defining
|
||||
CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the
|
||||
working setting (that allowed the bootp/tftp process) across the eth_reset
|
||||
operation.
|
||||
|
||||
|
||||
IV FOR DEVELOPERS....
|
||||
|
||||
If you would like to fix/extend/etc. this driver, feel free to do so; just
|
||||
be sure you can test the modified version on the 3c905B-TX cards that the
|
||||
driver was originally designed for. This section of this document gives
|
||||
some information that might be relevant to a programmer.
|
||||
|
||||
A. Main Entry Point
|
||||
|
||||
a3c90x_probe is the main entry point for this driver. It is referred
|
||||
to in an array in 'config.c'.
|
||||
|
||||
B. Other Important Functions
|
||||
|
||||
The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and
|
||||
a3c90x_disable are static functions that EtherBoot finds out about
|
||||
as a result of a3c90x_probe setting entries in the nic structure
|
||||
for them. The EtherBoot framework does not use interrupts. It is
|
||||
polled. All transmit and receive operations are initiated by the
|
||||
etherboot framework, not by an interrupt or by the driver.
|
||||
|
||||
C. Internal Functions
|
||||
|
||||
The following functions are internal to the driver:
|
||||
|
||||
a3c90x_internal_IssueCommand - sends a command to the 3c905b card.
|
||||
a3c90x_internal_SetWindow - shifts between one of eight register
|
||||
windows onboard the 3c90x. The bottom 16 bytes of the card's
|
||||
I/O space are multiplexed among 128 bytes, only 16 of which are
|
||||
visible at any one time. This SetWindow function selects one of
|
||||
the eight sets.
|
||||
a3c90x_internal_ReadEeprom - reads a word (16 bits) from the
|
||||
card's onboard nvram. This is NOT the BIOS boot rom. This is
|
||||
where the card stores such things as its hardware address.
|
||||
a3c90x_internal_WriteEeprom - writes a word (16 bits) to the
|
||||
card's nvram, and recomputes the eeprom checksum.
|
||||
a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
|
||||
card's nvram. Used by the above routine.
|
||||
a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
|
||||
card's nvram. Used by the above routine.
|
||||
|
||||
D. Globals
|
||||
|
||||
All global variables are inside a global structure named INF_3C90X.
|
||||
So, wherever you see that structure referenced, you know the variable
|
||||
is a global. Just keeps things a little neater.
|
||||
|
||||
E. Enumerations
|
||||
|
||||
There are quite a few enumerated type definitions for registers and
|
||||
so forth, many for registers that I didn't even touch in the driver.
|
||||
Register types start with 'reg', window numbers (for SetWindow)
|
||||
start with 'win', and commands (for IssueCommand) start with 'cmd'.
|
||||
Register offsets also include an indication in the name as to the
|
||||
size of the register (_b = byte, _w = word, _l = long), and which
|
||||
window the register is in, if it is windowed (0-7).
|
||||
|
||||
F. Why the 'a3c90x' name?
|
||||
|
||||
I had to come up with a letter at the beginning of all of the
|
||||
identifiers, since 3com so conveniently had their name start with a
|
||||
number. Another driver used 't' (for 'three'?); I chose 'a' for
|
||||
no reason at all.
|
||||
|
||||
Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re
|
||||
working around the 3C905 hardware bug mentioned above:
|
||||
|
||||
Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards
|
||||
that fail to load and run the boot program the first time around. If
|
||||
they have a "Lucent" rather than a "Broadcom" chipset these cards have
|
||||
a configuration bug that causes a hang when trying to load the boot
|
||||
program from the PROM, if you try to use them right out of the box.
|
||||
|
||||
The boot program in this floppy is the file named 3c905b-tpo100.rom
|
||||
from Etherboot version 4.6.10, compiled with the bugfix parameter
|
||||
|
||||
CFG_3C90X_BOOTROM_FIX
|
||||
|
||||
You have to take the chip off the card and boot the system once using
|
||||
this floppy. Once loaded from the floppy, the boot program will access
|
||||
the card and change some setting in it, correcting the problem. After
|
||||
that you may use either this boot program or the normal one, compiled
|
||||
without this bugfix parameter, to boot the machine from the PROM chip.
|
||||
|
||||
[Any recent Etherboot version should do, not just 4.6.10 - Ed.]

You can use the netboot support to download OS images from a network.
|
||||
Nearly all the device drivers are coming from the network-based boot
|
||||
loader, Etherboot. Please visit its web page. They have rich
|
||||
documentations so you will be able to get useful information from there.
|
||||
The URL is <http://etherboot.sourceforge.net/>.
|
||||
|
||||
These below are common options for configure. Perhaps you may not need
|
||||
to specify them.
|
||||
|
||||
--disable-packet-retransmission
|
||||
Turns off packet retransmission. Use it on an empty network, where
|
||||
no packet collision can happen.
|
||||
|
||||
--enable-pci-direct
|
||||
Define this for PCI BIOSes that do not implement BIOS32 or not
|
||||
correctly.
|
||||
|
||||
--enable-diskless
|
||||
Enable the diskless support. If specified, you will get two optional
|
||||
images, called "nbgrub" and "pxegrub". The former is the ``Net Boot
|
||||
Image Proposal'' format, which is used by Etherboot and Netboot, while
|
||||
the latter is the ``Preboot Execution Environment" format, which is
|
||||
used by a PXE ROM. You may buy a PXE ROM from some companies.
|
||||
|
||||
Here is the information about the device drivers. They are all disabled
|
||||
by default, so you must specify configure options to enable drivers you
|
||||
want to use. Some drivers have extra per-driver options, so the extra
|
||||
options are also described below.
|
||||
|
||||
Caution: You should enable them as you need. Don't enable any
|
||||
unnecessary driver, because GRUB might crash if you include too many
|
||||
drivers at the same time.

|

Thu Dec 6 22:40:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
|
||||
|
||||
* disabled all "advanced" features; this should make the code more reliable
|
||||
|
||||
* reorganized the reset function
|
||||
|
||||
* always reset the address port, so that autoprobing will continue working
|
||||
|
||||
* some cosmetic changes
|
||||
|
||||
* 2.5
|
||||
|
||||
Thu Dec 5 21:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
|
||||
|
||||
* tested the code against a CS8900 card
|
||||
|
||||
* lots of minor bug fixes and adjustments
|
||||
|
||||
* this is the first release, that actually works! it still requires some
|
||||
changes in order to be more tolerant to different environments
|
||||
|
||||
* 4
|
||||
|
||||
Fri Nov 22 23:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
|
||||
|
||||
* read the manuals for the CS89x0 chipsets and took note of all the
|
||||
changes that will be neccessary in order to adapt Russel Nelson's code
|
||||
to the requirements of a BOOT-Prom
|
||||
|
||||
* 6
|
||||
|
||||
Thu Nov 19 22:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
|
||||
|
||||
* Synched with Russel Nelson's current code (v1.00)
|
||||
|
||||
* 2
|
||||
|
||||
Thu Nov 12 18:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
|
||||
|
||||
* Cleaned up some of the code and tried to optimize the code size.
|
||||
|
||||
* 1.5
|
||||
|
||||
Sun Nov 10 16:30:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
|
||||
|
||||
* First experimental release. This code compiles fine, but I
|
||||
have no way of testing whether it actually works.
|
||||
|
||||
* I did not (yet) bother to make the code 16bit aware, so for
|
||||
the time being, it will only work for Etherboot/32.

has the following difference.
|
||||
Changed symbol tulip/TULIP to davicom/DAVICOM
|
||||
Deleted some code that did not use in this driver.
|
||||
Used chain-strcture to replace ring structure
|
||||
for both TX/RX descriptor.
|
||||
Allocated two tx descriptor.

relatively busy network. The DE422 has been tested a little.
|

|
||||
This driver will NOT work for the DE203, DE204 and DE205 series of
|
||||
cards, since they have a new custom ASIC in place of the AMD LANCE
|
||||
chip. See the 'ewrk3.c' driver in the Linux source tree for running
|
||||
those cards.
|
||||
|

I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
|
||||
a DECstation 5000/200.

Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
|
||||
driver.
|
||||
|
||||
The original DEPCA card requires that the ethernet ROM address counter
|
||||
be enabled to count and has an 8 bit NICSR. The ROM counter enabling is
|
||||
only done when a 0x08 is read as the first address octet (to minimise
|
||||
the chances of writing over some other hardware's I/O register). The
|
||||
NICSR accesses have been changed to byte accesses for all the cards
|
||||
supported by this driver, since there is only one useful bit in the MSB
|
||||
(remote boot timeout) and it is not used. Also, there is a maximum of
|
||||
only 48kB network RAM for this card. My thanks to Torbjorn Lindh for
|
||||
help debugging all this (and holding my feet to the fire until I got it
|
||||
right).
|
||||
|
||||
The DE200 series boards have on-board 64kB RAM for use as a shared
|
||||
memory network buffer. Only the DE100 cards make use of a 2kB buffer
|
||||
mode which has not been implemented in this driver (only the 32kB and
|
||||
64kB modes are supported [16kB/48kB for the original DEPCA]).
|
||||
|
||||
At the most only 2 DEPCA cards can be supported on the ISA bus because
|
||||
there is only provision for two I/O base addresses on each card (0x300
|
||||
and 0x200). The I/O address is detected by searching for a byte sequence
|
||||
in the Ethernet station address PROM at the expected I/O address for the
|
||||
Ethernet PROM. The shared memory base address is 'autoprobed' by
|
||||
looking for the self test PROM and detecting the card name. When a
|
||||
second DEPCA is detected, information is placed in the base_addr
|
||||
variable of the next device structure (which is created if necessary),
|
||||
thus enabling ethif_probe initialization for the device. More than 2
|
||||
EISA cards can be supported, but care will be needed assigning the
|
||||
shared memory to ensure that each slot has the correct IRQ, I/O address
|
||||
and shared memory address assigned.
|
||||
|
||||
************************************************************************
|
||||
|
||||
NOTE: If you are using two ISA DEPCAs, it is important that you assign
|
||||
the base memory addresses correctly. The driver autoprobes I/O 0x300
|
||||
then 0x200. The base memory address for the first device must be less
|
||||
than that of the second so that the auto probe will correctly assign the
|
||||
I/O and memory addresses on the same card. I can't think of a way to do
|
||||
this unambiguously at the moment, since there is nothing on the cards to
|
||||
tie I/O and memory information together.
|
||||
|
||||
I am unable to test 2 cards together for now, so this code is
|
||||
unchecked. All reports, good or bad, are welcome.
|
||||
|
||||
************************************************************************
|
||||
|
||||
The board IRQ setting must be at an unused IRQ which is auto-probed
|
||||
using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
|
||||
{2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is
|
||||
really IRQ9 in machines with 16 IRQ lines.
|
||||
|
||||
No 16MB memory limitation should exist with this driver as DMA is not
|
||||
used and the common memory area is in low memory on the network card (my
|
||||
current system has 20MB and I've not had problems yet).
|
||||
|
||||
The ability to load this driver as a loadable module has been added. To
|
||||
utilise this ability, you have to do <8 things:
|
||||
|
||||
0) have a copy of the loadable modules code installed on your system.
|
||||
1) copy depca.c from the /linux/drivers/net directory to your favourite
|
||||
temporary directory.
|
||||
2) if you wish, edit the source code near line 1530 to reflect the I/O
|
||||
address and IRQ you're using (see also 5).
|
||||
3) compile depca.c, but include -DMODULE in the command line to ensure
|
||||
that the correct bits are compiled (see end of source code).
|
||||
4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
|
||||
kernel with the depca configuration turned off and reboot.
|
||||
5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
|
||||
[Alan Cox: Changed the code to allow command line irq/io assignments]
|
||||
[Dave Davies: Changed the code to allow command line mem/name
|
||||
assignments]
|
||||
6) run the net startup bits for your eth?? interface manually
|
||||
(usually /etc/rc.inet[12] at boot time).
|
||||
7) enjoy!
|
||||
|
||||
Note that autoprobing is not allowed in loadable modules - the system is
|
||||
already up and running and you're messing with interrupts.
|
||||
|
||||
To unload a module, turn off the associated interface
|
||||
'ifconfig eth?? down' then 'rmmod depca'.
|
||||
|
||||
To assign a base memory address for the shared memory when running as a
|
||||
loadable module, see 5 above. To include the adapter name (if you have
|
||||
no PROM but know the card name) also see 5 above. Note that this last
|
||||
option will not work with kernel built-in depca's.
|
||||
|
||||
The shared memory assignment for a loadable module makes sense to avoid
|
||||
the 'memory autoprobe' picking the wrong shared memory (for the case of
|
||||
2 depca's in a PC).
|
||||
|
||||
************************************************************************
|
||||
Support for MCA EtherWORKS cards added 11-3-98.
|
||||
Verified to work with up to 2 DE212 cards in a system (although not
|
||||
fully stress-tested).
|
||||
|
||||
Currently known bugs/limitations:
|
||||
|
||||
Note: with the MCA stuff as a module, it trusts the MCA configuration,
|
||||
not the command line for IRQ and memory address. You can
|
||||
specify them if you want, but it will throw your values out.
|
||||
You still have to pass the IO address it was configured as
|
||||
though.

Etherboot - BOOTP/TFTP Bootstrap Program

Intel EEPRO/10 NIC driver for Etherboot
|

Adapted from Linux eepro.c from kernel 2.2.17
|
||||
|
||||
This board accepts a 32 pin EEPROM (29C256), however a test with a
|
||||
27C010 shows that this EPROM also works in the socket, but it's not clear
|
||||
how repeatably. The two top address pins appear to be held low, thus
|
||||
the bottom 32kB of the 27C010 is visible in the CPU's address space.
|
||||
To be sure you could put 4 copies of the code in the 27C010, then
|
||||
it doesn't matter whether the extra lines are held low or high, just
|
||||
hopefully not floating as CMOS chips don't like floating inputs.
|
||||
|
||||
Be careful with seating the EPROM as the socket on my board actually
|
||||
has 34 pins, the top row of 2 are not used.

/* Philosophy of this driver.
|
||||
*
|
||||
* Probing:
|
||||
*
|
||||
* Using the pci.c functions of the Etherboot code, the 82557 chip is detected.
|
||||
* It is verified that the BIOS initialized everything properly and if
|
||||
* something is missing it is done now.
|
||||
*
|
||||
*
|
||||
* Initialization:
|
||||
*
|
||||
*
|
||||
* The chip is then initialized to "know" its ethernet address, and to
|
||||
* start recieving packets. The Linux driver has a whole transmit and
|
||||
* recieve ring of buffers. This is neat if you need high performance:
|
||||
* you can write the buffers asynchronously to the chip reading the
|
||||
* buffers and transmitting them over the network. Performance is NOT
|
||||
* an issue here. We can boot a 400k kernel in about two
|
||||
* seconds. (Theory: 0.4 seconds). Booting a system is going to take
|
||||
* about half a minute anyway, so getting 10 times closer to the
|
||||
* theoretical limit is going to make a difference of a few percent.
|
||||
*
|
||||
*
|
||||
* Transmitting and recieving.
|
||||
*
|
||||
* We have only one transmit descriptor. It has two buffer descriptors:
|
||||
* one for the header, and the other for the data.
|
||||
* We have only one receive buffer. The chip is told to recieve packets,
|
||||
* and suspend itself once it got one. The recieve (poll) routine simply
|
||||
* looks at the recieve buffer to see if there is already a packet there.
|
||||
* if there is, the buffer is copied, and the reciever is restarted.
|
||||
*
|
||||
* Caveats:
|
||||
*
|
||||
* The etherboot framework moves the code to the 32k segment from

The confusion between 60/64 and 1514/1518 arose because the NS8390
|
||||
counts the 4 byte frame checksum in the incoming packet, but not
|
||||
in the outgoing packet. 60/1514 are the correct numbers for most
|
||||
if not all of the other NIC controllers. I will be retiring the
|
||||
64/1518 defines in the lead-up to 5.0.

thus the unusual location of the SCB at 0x0008.

cleaner.

That's it: only 86 bytes to set up the beast, including every extra

command available. The 170 byte buffer at DUMP_DATA is shared between the
|
||||
Dump command (called only by the diagnostic program) and the SetMulticastList
|
||||
command.
|
||||
|
||||
To complete the memory setup you only have to write the station address at
|
||||
SA_OFFSET and create the Tx & Rx buffer lists.
|
||||
|
||||
The Tx command chain and buffer list is setup as follows:
|
||||
A Tx command table, with the data buffer pointing to...
|
||||
A Tx data buffer descriptor. The packet is in a single buffer, rather than
|
||||
chaining together several smaller buffers.
|
||||
A NoOp command, which initially points to itself,
|
||||
And the packet data.
|
||||
|
||||
A transmit is done by filling in the Tx command table and data buffer,
|
||||
re-writing the NoOp command, and finally changing the offset of the last
|
||||
command to point to the current Tx command. When the Tx command is finished,
|
||||
it jumps to the NoOp, when it loops until the next Tx command changes the
|
||||
"link offset" in the NoOp. This way the 82586 never has to go through the
|
||||
slow restart sequence.
|
||||
|
||||
The Rx buffer list is set up in the obvious ring structure. We have enough
|
||||
memory (and low enough interrupt latency) that we can avoid the complicated
|
||||
Rx buffer linked lists by alway associating a full-size Rx data buffer with
|
||||
each Rx data frame.
|
||||
|
||||
I currently use one transmit buffer starting at TX_BUF_START (0x0100), and
|
||||
use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

Etherboot DEC Tulip driver

adapted by Ken Yap from

FreeBSD netboot DEC 21143 driver
|

|

Author: David Sharp
|

date: Nov/98
|
||||
|
||||
Known to work on DEC DE500 using 21143-PC chipset.
|
||||
Even on cards with the same chipset there can be
|
||||
incompatablity problems with the way media selection
|
||||
and status LED settings are done. See comments below.
|
||||
|
||||
Some code fragments were taken from verious places,
|
||||
Ken Yap's etherboot, FreeBSD's if_de.c, and various
|
||||
Linux related files. DEC's manuals for the 21143 and
|
||||
SROM format were very helpful. The Linux de driver
|
||||
development page has a number of links to useful
|
||||
related information. Have a look at:

|
||||
Following email from Hyun-Joon Cha, added a disable routine, otherwise
|
||||
NIC remains live and can crash the kernel later.
|
||||
|
||||
4 Feb 2000 espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
|
||||
Shuffled things around, removed the leftovers from the 8129 support
|
||||
that was in the Linux driver and added a bit more 8139 definitions.
|
||||
Moved the 8K receive buffer to a fixed, available address outside the
|
||||
0x98000-0x9ffff range. This is a bit of a hack, but currently the only
|
||||
way to make room for the Etherboot features that need substantial amounts
|
||||
of code like the ANSI console support. Currently the buffer is just below
|
||||
0x10000, so this even conforms to the tagged boot image specification,
|
||||
which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My
|
||||
interpretation of this "reserved" is that Etherboot may do whatever it
|
||||
likes, as long as its environment is kept intact (like the BIOS
|
||||
variables). Hopefully fixed rtl_poll() once and for all. The symptoms
|
||||
were that if Etherboot was left at the boot menu for several minutes, the
|
||||
first eth_poll failed. Seems like I am the only person who does this.
|
||||
First of all I fixed the debugging code and then set out for a long bug
|
||||
hunting session. It took me about a week full time work - poking around
|
||||
various places in the driver, reading Don Becker's and Jeff Garzik's Linux
|
||||
driver and even the FreeBSD driver (what a piece of crap!) - and
|
||||
eventually spotted the nasty thing: the transmit routine was acknowledging
|
||||
each and every interrupt pending, including the RxOverrun and RxFIFIOver
|
||||
interrupts. This confused the RTL8139 thoroughly. It destroyed the
|
||||
Rx ring contents by dumping the 2K FIFO contents right where we wanted to
|
||||
get the next packet. Oh well, what fun.
|
||||
|
||||
18 Jan 2000 mdc@thinguin.org (Marty Connor)
|
||||
Drastically simplified error handling. Basically, if any error
|
||||
in transmission or reception occurs, the card is reset.
|
||||
Also, pointed all transmit descriptors to the same buffer to
|
||||
save buffer space. This should decrease driver size and avoid
|
||||
corruption because of exceeding 32K during runtime.
|
||||
|
||||
28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
|
||||
rtl_poll was quite broken: it used the RxOK interrupt flag instead
|
||||
of the RxBufferEmpty flag which often resulted in very bad
|
||||
transmission performace - below 1kBytes/s.

How I added the SIS900 card to Etherboot
|
||||
|
||||
Author: Marty Connor (mdc@thinguin.org)
|
||||
|
||||
Date: 25 Febrary 2001
|
||||
|
||||
Description:
|
||||
|
||||
This file is intended to help people who want to write an Etherboot
|
||||
driver or port another driver to Etherboot. It is a starting point.
|
||||
Perhaps someday I may write a more detailed description of writing an
|
||||
Etherboot driver. This text should help get people started, and
|
||||
studying sis900.[ch] should help show the basic structure and
|
||||
techniques involved in writing and Etherboot driver.
|
||||
|
||||
***********************************************************************
|
||||
|
||||
0. Back up all the files I need to modify:
|
||||
|
||||
cd etherboot-4.7.20/src
|
||||
cp Makefile Makefile.orig
|
||||
cp config.c config.c.orig
|
||||
cp pci.h pci.h.orig
|
||||
cp NIC NIC.orig
|
||||
cp cards.h cards.h.orig
|
||||
|
||||
1. Edit src/Makefile to add SIS900FLAGS to defines
|
||||
|
||||
SIS900FLAGS= -DINCLUDE_SIS900
|
||||
|
||||
2. edit src/pci.h to add PCI signatures for card
|
||||
|
||||
#define PCI_VENDOR_ID_SIS 0x1039
|
||||
#define PCI_DEVICE_ID_SIS900 0x0900
|
||||
#define PCI_DEVICE_ID_SIS7016 0x7016
|
||||
|
||||
3. Edit src/config.c to add the card to the card probe list
|
||||
|
||||
#if defined(INCLUDE_NS8390) || defined(INCLUDE_EEPRO100) ||
|
||||
defined(INCLUDE_LANCE) || defined(INCLUDE_EPIC100) ||
|
||||
defined(INCLUDE_TULIP) || defined(INCLUDE_OTULIP) ||
|
||||
defined(INCLUDE_3C90X) || defined(INCLUDE_3C595) ||
|
||||
defined(INCLUDE_RTL8139) || defined(INCLUDE_VIA_RHINE) ||
|
||||
defined(INCLUDE_SIS900) || defined(INCLUDE_W89C840)
|
||||
|
||||
... and ...
|
||||
|
||||
#ifdef INCLUDE_SIS900
|
||||
{ PCI_VENDOR_ID_SIS, PCI_DEVICE_ID_SIS900,
|
||||
"SIS900", 0, 0, 0, 0},
|
||||
{ PCI_VENDOR_ID_SIS, PCI_DEVICE_ID_SIS7016,
|
||||
"SIS7016", 0, 0, 0, 0},
|
||||
#endif
|
||||
|
||||
... and ...
|
||||
|
||||
#ifdef INCLUDE_SIS900
|
||||
{ "SIS900", sis900_probe, pci_ioaddrs },
|
||||
#endif
|
||||
|
||||
4. Edit NIC to add sis900 and sis7016 to NIC list
|
||||
|
||||
# SIS 900 and SIS 7016
|
||||
sis900 sis900 0x1039,0x0900
|
||||
sis7016 sis900 0x1039,0x7016
|
||||
|
||||
5. Edit cards.h to add sis900 probe routine declaration
|
||||
|
||||
#ifdef INCLUDE_SIS900
|
||||
extern struct nic *sis900_probe(struct nic *, unsigned short *
|
||||
PCI_ARG(struct pci_device *));
|
||||
#endif

At this point, you can begin creating your driver source file. See
|

the "Writing and Etherboot Driver" section of the Etherboot
|
||||
documentation for some hints. See the skel.c file for a starting
|
||||
point. If there is a Linux driver for the card, you may be able to
|

use that. Copy and learn from existing Etherboot drivers (this is GPL
|

|
||||
Join the etherboot-developers and etherboot-users mailing lists
|

This is a tulip and clone driver for Etherboot. See the revision
|
||||
history in the tulip.c file for information on changes. This version
|
||||
of the driver incorporates changes from Bob Edwards and Paul Mackerras
|
||||
who cantributed changes to support the TRENDnet TE100-PCIA NIC which
|
||||
uses a genuine Intel 21143-PD chipset. There are also various code
|
||||
cleanups to make time-based activities more reliable.
|
||||
|
||||
Of course you have to have all the usual Etherboot environment
|
||||
(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
|
||||
(7.16.99) or later of the tulip.c driver compiled in to support some
|
||||
MX98715 based cards. That file is available at:
|
||||
|
||||
http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
|
||||
|
||||
NOTES
|
||||
|
||||
I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
|
||||
a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
|
||||
both 10 and 100 mbits. Other cards based on the tulip family may work as
|
||||
well.
|
||||
|
||||
These cards are about 20$US, are supported by Linux and now Etherboot,
|
||||
and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
|
||||
10/100 half/full duplex. It seems like a pretty good value compared to
|
||||
some of the pricier cards, and can lower the cost of building/adapting
|
||||
thin client workstations substantially while giving a considerable
|
||||
performance increase.
|
||||
|
||||
On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver
|
||||
lets the card choose the fastest speed it can negotiate with the peer
|
||||
device. On other cards, it chooses 10mbit half-duplex.
|
||||
|
||||
I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
|
||||
According to the data sheet the MX98715A supports up to 64K (27C512)
|
||||
EPROMs,
|
||||
|
||||
I've liberally commented the code and header files in the hope that it
|
||||
will help the next person who hacks the code or needs to support some
|
||||
tulip clone card, or wishes to add functionality.
|
||||
|
||||
Anyway, please test this if you can on your tulip based card, and let
|
||||
me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de)
|
||||
know how things go. I also would appreciate code review by people who
|
||||
program. I'm a strong believer in "another set of eyes".
|
||||

||||

|
