Change the type of BUFADDR from int to char *.
Use a virtual track to make sure that one track fits in the
buffer.

a bios drive for a CD-ROM is often assigned to greater than
0x88.

function.
(init_device_map) [__linux__]: Probe ATARAID disks.

well.
* lib/device.c (check_device): If DEVICE is empty, just return
1.

Also recognize the right key for the selection of a boot entry.
Suggested by Adam Lackorzynski <adam@os.inf.tu-dresden.de>.
* stage2/boot.c (load_image): Rewrite the Linux booting support
radically. Now it should work even on a machine having, say,
only 128KB, theoretically. Of course, GRUB itself doesn't work
on such a system, though.
(load_initrd): Initialize LH based on CUR_ADDR, because the
location becomes dynamic.
* stage2/shared.h (LINUX_MAX_SETUP_SECTS): Set to 64.

ARP entry for the gateway. If SVR is specified, clear out the
ARP entry for the server. Reported by Uwe Dannowski
<ud3@ira.uka.de>.
Define the behavior of the boot loader when the load end address
and the bss end address are zero in the Multiboot Specification,
and add the support into GRUB. I've modified a patch from Yuri
Zaporogets <yuriz@ukr.net>.
* stage2/boot.c (load_image): In the case of Multiboot a.out
kludge, set the load end address to the load address plus the
size of the OS image file, if it is zero. Similarly, set the bss
end address to the load end address, if it is zero.
* util/mbchk.c (check_multiboot): Don't check if the load
address is greater than or equal to the load end address, if the
load end address is zero. Don't check if the load end address is
greater than the bss end address, if the bss end address is
zero. And, don't check if the load end address is less than or
equal to the entry address, if the load end address is zero.
* docs/multiboot.texi (The address fields of Multiboot header):
Added descriptions about the behavior of the boot loader when
LOAD_END_ADDR is zero and BSS_END_ADDR is zero.
* stage2/builtins.c [GRUB_UTIL] (dump_func): New function.
[GRUB_UTIL] (builtin_dump): New variable.
(builtin_table) [GRUB_UTIL]: Added a pointer to BUILTIN_DUMP.
* util/grub-install.in: Make sure that GRUB reads the same
images as the host operating system by comparing the result of
running the command "dump" with the contents of the OS file.
* stage2/boot.c (linux_mem_size): New variable.
(load_image): Check a mem= option and set LINUX_MEM_SIZE to the
specified memory size, if any. Otherwise, to zero. When an
overflow is detected, use LINUX_INITRD_MAX_ADDRESS instead.
(load_initrd): If LINUX_MEM_SIZE is non-zero, use it instead of
the actual memory size.
* stage2/char_io.c (safe_parse_maxint): Use ERR_NUMBER_OVERFLOW
instead of ERR_NUMBER_PARSING, when an overflow occurs.
* stage2/common.c [!STAGE1_5] (err_list): Added
ERR_NUMBER_OVERFLOW.

(use_pager) [!STAGE1_5]: Likewise.
(grub_putchar) [!STAGE1_5]: if C is a newline and COUNT_LINES is
not -1, count up the number of lines. If it exceeds the maximum
number of lines minus 2, show a message and wait for input of
return key. "minus 2" is to reserve space for the message
printed by this internal pager.
* stage2/cmdline.c (enter_cmdline): If USE_PAGER is true, set
COUNT_LINES to zero, before running a command, and reset
COUNT_LINES to -1 after that.
* stage2/shared.h (max_lines) [!STAGE1_5]: Declared.
(count_lines) [!STAGE1_5]: Likewise.
