1999-03-27 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>
* grub/asmstub.c (set_attrib): Use inch and addch, instead of
chgat, because chgat doesn't work as expected.
1999-03-26 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>
* grub/asmstub.c (grub_stage2) [HAVE_LIBCURSES]: Call nodelay.
(checkkey) [HAVE_LIBCURSES]: If getting an input character, then
ungetch it, because checkkey shouldn't modify the input queue.
Use file descriptors instead of file pointers to support
>4GB disks in Linux.
* grub/asmstub.c (grub_stage2): Call close instead of fclose.
(get_diskinfo): Call open instead of fopen.
(biosdisk) [__linux__]: Use _llseek instead of lseek.
(biosdisk): Call read instead of fread.
Add options so that the user can specify the config file.
* grub/Makefile.am (CPPFLAGS): Use -fwritable-strings, because
grub assumes that all strings resides at the data section.
* grub/main.c: Define NO_REMAPPING_LIBC_FUNCTIONS before including
shared.h.
(OPT_CONFIG_FILE): New macro.
(OPT_INSTALL_PARTITION): Likewise.
(OPT_BOOT_DRIVE): Likewise.
(longopts): Add new options, config-file, install-partition and
boot-drive.
(usage): Add the documentation for them.
(main): Add handling code for OPT_CONFIG_FILE, OPT_INSTALL_PARTITION
and OPT_BOOT_DRIVE.
* grub/asmstub.c: Define NO_REMAPPING_LIBC_FUNCTIONS before including
shared.h.
(config_file): Make it char * instead of char [].
(getrtsecs): Return current time instead of 0xff.
* shared_src/shared.h [NO_REMAPPING_LIBC_FUNCTIONS]: Don't define
libc-API-compatible function names.

1999-03-25 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>
* char_io.c (get_cmdline): Call cl_setcpos even if lpos == llen,
because ncurses won't update the cursor position.
* grub/main.c (OPT_HOLD): New macro.
(longopts): New option --hold.
(usage): Add the documentation about --hold.
(main): Set hold if --hold is specified. Wait until cleared.
1999-03-22 Gordon Matzigkeit <gord@trick.fig.org>
* shared_src/cmdline.c (enter_cmdline): Check the return value of
set_device in the `root' command.
* shared_src/char_io.c (memcheck): Special-case cur_part_desc and
reenable memory checking.
1999-03-21 Gordon Matzigkeit <gord@trick.fig.org>
* shared_src/boot.c (load_image): Make sure we use the mapped
address before actually writing data to memaddr.
* shared_src/char_io.c (get_cmdline): Only zero-terminate if there
were leading blanks. This prevents accidental truncation of
commands.
* grub/asmstub.c (get_diskinfo): Cache device geometries as well
as file handles.
Use the Linux HDIO_GETGEO ioctl to make a better guess at hard
disk geometries.
1999-03-16 Gordon Matzigkeit <gord@trick.fig.org>
* shared_src/shared.h (geometry_t): Delete typedef, until we
actually use it.
1999-03-16 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>
* shared_src/asm.S (biosdisk): Use a structure for geometry
instead of a integer.

second argument, and fill a geometry in it. Return 1 if an error
occurs, otherwise return 0.

* shared_src/cmdline.c (enter_cmdline): Declare dest_geom as
struct geometry.
* shared_src/disk_io.c (buf_geom): Declare as struct geometry.

(enter_cmdline): Only abort the boot if we are in a script.
* shared_src/stage2.c (run_menu): Change prompts to "grub edit> ".
* shared_src/char_io.c (memcheck): Use RAW_ADDR to compute memory
locations.
(get_cmdline): Change the `goto next line' code to account for
newlines deleting to end of line under curses.
* Innumerable cleanups to fix warnings. There are still too many
typecasts in the wrong places (int variables used to hold
pointers, then casted to a pointer type), but things look better.
* configure.in (CPPFLAGS): Bump up GCC warnings to -Wall
-Wmissing-prototypes -Wunused.
* shared_src/shared.h: Delete stupid declarations, and totally
rearrange for clarity.
(inb, outb): Move to cmdline.c, since it's only used there.
(print_possibilities, fsmax, fsys_table): Move definitions to
disk_io.c.
* grub/asmstub.c: Fill in more stubs.

clash with curses.
* shared_src/stage2.c (timeout): Rename to grub_timeout.

* shared_src/char_io.c (getkey): Delete, because it's useless.
* shared_src/shared.h: Resolve name clashes with libc by renaming
overlapping functions to have grub_ prefixes, then defining
macros.
* grub/asmstub.c (start_stage2): Make some assertions about our
scratch memory area.
* shared_src/shared.h (end): Delete declaration.
(RAW_ADDR, RAW_SEG): Macros to redirect /sbin/grub memory requests
through grub_scratch_mem.

contiguous memory.
(get_code_end): Implement, simulating with a malloced area.
grub/asmstub.c (start_stage2): Initialize grub_scratch_mem.
* shared_src/asm.S (get_mem_map): Some BIOSes expect the high word
of %eax to be zero.
(get_code_end): Move this from common.c so that we can stub it out
in the simulator.
* debian/rules: Make sure info files end up in /usr/info, not
/info.
1999-03-10 Gordon Matzigkeit <gord@trick.fig.org>
* shared_src/asm.S (biosdisk): Make LBA mode work correctly. From
OKUJI Yoshinori.
Unconditionally define NO_INT13_FALLBACK until we release GRUB
0.6. This will help debug any problems with the LBA support until
then.
1999-03-09 Gordon Matzigkeit <gord@trick.fig.org>
* shared_src/asm.S (biosdisk): Compute location of
disk_address_packet correctly. From OKUJI Yoshinori.

Mach-style partition naming.
* shared_src/stage2.c (run_menu): Don't say it was a failure if
enter_cmdline returns nonzero... just wait for a key.
* shared_src/cmdline.c (enter_cmdline): Return nonzero, and avoid
the fallback command if we did an install.
* shared_src/asm.S (_start): New explicit symbol to supress
warnings.
* e2fs_stage1_5/Makefile.am (NO_FANCY_STUFF): Renamed to STAGE1_5,
since that describes this conditional more accurately.
* fat_stage1_5/Makefile.am: Likewise.
* ffs_stage1_5/Makefile.am: Likewise.
* shared_src/asm.S: Likewise.
* shared_src/char_io.c: Likewise.

* shared_src/disk_io.c: Likewise.
* shared_src/fsys_ext2fs.c: Likewise.
* shared_src/fsys_ffs.c: Likewise.
* shared_src/shared.h: Likewise.
1999-03-07 Gordon Matzigkeit <gord@trick.fig.org>
* configure.in (SHARED_SRC_RULES): Automatically generate
Makefile dependencies for files in shared_src.
e2fs_stage1_5/Makefile.am: Use them.
fat_stage1_5/Makefile.am: Likewise.
ffs_stage1_5/Makefile.am: Likewise.
grub/Makefile.am: Likewise.
stage2/Makefile.am: Likewise.
stage2_debug/Makefile.am: Likewise.
* shared_src/disk_inode.h: Fix typo: i_ic shouldn't be defined.
* shared_src/fsys_ffs.c (block_map): Make static, since this
function isn't used outside of its defining file.
* shared_src/disk_io.c [NO_FANCY_STUFF]: Eliminate a whole bunch
more functions from the stage1.5. From OKUJI Yoshinori.

the BIOS extension detection code.
(biosdisk) [AWARD_INT13_EXTENSIONS]: Preliminary implementation
of Award's encoding of cylinder bits 10 and 11.

substituted into the Makefile.
* e2fs_stage1_5/Makefile.am (pkgdatadir): Install files in

install files.
* shared_src/asm.S (version_string): Set the version string from
the VERSION specified in configure.in.
* Change all Makefiles into Makefile.ams. Many major build
environment changes to get Automake/Autoconf working nicely.

* NEWS: Moved from docs/NEWS.
* configure.in, acinclude.m4: New files for Autoconf. From OKUJI
Yoshinori.
* AUTHORS, INSTALL: New files.
1999-02-24 Gordon Matzigkeit <gord@trick.fig.org>
* stage1/stage1.S (after_BPB): Do a hard disk probe first, so that
we can work with IDE floppies (like the LS-120).
* Run GNU Indent on */*.[ch].
1999-02-21 Gordon Matzigkeit <gord@trick.fig.org>
* debian: Add to the distribution, since we maintain the GRUB
Debian package ourselves.
* grub/asmstub.c: New file to implement stubbed assembly functions
under Unix.
* stage1/Makefile: Delete spurious dependencies on Makefile.
* stage2/Makefile: Likewise.
* stage2_debug/Makefile: Likewise.
* grub/Makefile: Likewise.
* shared_src/fsys_ext2fs.c (ext2fs_dir): Follow symbolic links
rather than giving an error.
* shared_src/common.c (err_list): Use labeled elements to
associate messages with error codes.

GNU standards.
* stage2/Makefile: Likewise.
* e2fs_stage1_5/Makefile: Likewise.
* fat_stage1_5/Makefile: Likewise.
* ffs_stage1_5/Makefile: Likewise.
1999-02-20 Gordon Matzigkeit <gord@trick.fig.org>
* docs/index.html: Rename to grub.html, so that we don't hide
files in this directory from a web browser.
1999-02-15 Gordon Matzigkeit <gord@trick.fig.org>
* Makefile.end (PROGS): Add grub.
* grub/main.c: New file.
* grub/Makefile: New directory to contain the stage2 Unix program.
* shared_src/cmdline.c: Use substring.

* shared_src/fsys_fat.c: Likewise.
* shared_src/fsys_ffs.c: Likewise.
* shared_src/stage2.c: Likewise.
* shared_src/shared.h: Delete strcmp, declare substring.
* shared_src/char_io.c (strcmp): Rename to `substring', because
this function doesn't behave the same as libc's strcmp.

* shared_src/shared.h: (addr32, data32): Delete definitions.
* stage1/stage1.S: Modify to use GAS's new .code16 semantics.
shared_src/asm.S: Likewise.
* configure: Test to see if the `addr32' instruction is supported.
Ian Lance Taylor says that GAS's interpretation of `.code16' has
changed. Older versions always generated 32-bit code, but
implicitly inserted addr32 and data32 when .code16 was given.
Newer versions generate 16-bit code, and require manual addr32 and
data32 overrides.
* shared_src/shared.h: Add some assertions to check that buffer
addresses are properly defined.

* e2fs_stage1_5/Makefile: Avoid gratuitous dependencies on
Makefile.
* fat_stage1_5/Makefile: Likewise.
* ffs_stage1_5/Makefile: Likewise.
* Makefile.end (PROGS): Add e2fs_stage1_5, fat_stage1_5, and
grubinst.
(distclean): New GNU standard rule.
1998-10-23 Gordon Matzigkeit <gord@trick.fig.org>
* configure: Accept `--host' as a synonym for `--target', and
accept a non-optional argument as the target name. Join the
prefix to the tool name with a hyphen.
* shared_src/disk_io.c (print_fsys_type): Always print the
partition type.
* shared_src/stage2.c (run_menu): Check to make sure that the
fallback entry is nonnegative.
(run_menu): For consistency, use `e' rather than enter to edit the
command entry.
