This is a big change on saving a default entry. This change
makes it possible to set up a quite robust system using GRUB.
Now we do not use the second sector of Stage 2 to store an
entry number but use the file /boot/grub/default. This file
must be generated by grub-set-default, although this file is
plain-text.
* util/grub-set-default.in: New file.
* util/grub-install.in (grub_set_default): New variable.
Use /grub instead of /boot/grub on OpenBSD as well as NetBSD.
Run grub-set-default to make a default file.
* util/Makefile.am (sbin_SCRIPTS): Added grub-set-default.
* stage2/stage2.c (run_menu): Change the fallback handling to
support multiple fallback entries.
(cmain): Likewise. Also, get a saved entry from a default file
if possible, before reading a config file.
* stage2/shared.h (DEFAULT_FILE_BUF): New macro.
(DEFAULT_FILE_BUFLEN): Likewise.
(CMDLINE_BUF): Set to DEFAULT_FILE_BUF + DEFAULT_FILE_BUFLEN.
(MENU_BUFLEN): Set to 0x8000 + PASSWORD_BUF - MENU_BUF.
(fallback_entry): Removed.
(fallback_entries): Declared.
(fallback_entryno): Likewise.
(MAX_FALLBACK_ENTRIES): New macro.
* stage2/cmdline.c (run_script): Use FALLBACK_ENTRYNO instead of
FALLBACK_ENTRY.
* stage2/builtins.c (fallback_entry): Removed.
(fallback_entryno): New variable.
(fallback_entries): Likewise.
(init_config): Initialize FALLBACK_ENTRYNO and FALLBACK_ENTRIES.
(fallback_func): Rewritten completely.
(savedefault_func): Likewise.
* docs/grub.texi (grub-set-default): New direntry.
(Installation): Describe grub-set-default for manual
installations.
(Making your system robust): New section.
(Booting once-only): New subsection.
(Booting fallback systems): Likewise.
(fallback): Describe multiple fallback entries.
(savedefault): Describe an optional argument.
(Invoking grub-set-default): New chapter.
(Future): Replaced with a description about GRUB 2.
* configure.ac (AC_CONFIG_FILES): Added util/grub-set-default.
* stage2/char_io.c (grub_isspace): Use a switch sentense instead
of an if sentense, because that reduces the size.
* lib/device.c (read_device_map): Change the max number of DRIVE
to 127 from 8. This was too strict.
* stage2/asm.S (stop_floppy): Call pusha and popa outside the
block of real mode code. Reported by Guillem Jover
<guillem@debian.org>.
* lib/device.c: Mangle __FreeBSD_* macro usage to support
kFreeBSD-based non-FreeBSD systems (i.e. GNU/kFreeBSD).
Implement runtime detection of version of kFreeBSD. Now if
we build against kFreeBSD 5.x headers the GRUB shell will work on
both 4.x and 5.x.
Replace `u_int_t' types with portable `unsigned int' and old
reference to `geometry' structure to new `geom' one.
* docs/menu.lst: Split GNU/kFreeBSD and GNU/kNetBSD as separate
options than FreeBSD and NetBSD, respectively. There are minor
differences now (different paths).
* docs/grub.texi (Making a GRUB bootable CD-ROM): minor edits,
including a few compatibility notes and a change to
-boot-load-size 4 for the mkisofs command.
* Makefile.am (AUTOMAKE_OPTIONS): Add "gnu".
* configure.ac: Update to work with automake 1.8, quote all
AC_DEFUN's correctly and provide descriptions for AC_DEFINE's.
* acinclude.m4: Likewise.
* acconfig.h: Removed.
* stage1/Makefile.am (.exec): Use suffix rules instead of pattern
rules.
* stage2/Makefile.am (.exec): Likewise.
* docs/grub.texi (Making a GRUB bootable CD-ROM): New section.
* stage2/disk_io.c (set_device): Use CH instead of *DEVICE to
test the first character of DEVICE, because DEVICE is
incremented.
Reported by Bernhard Treutwein.
* netboot/fsys_tftp.c (buf_fill): Cast 1 to unsigned short
explicitly so that the constant doesn't extend unsigned short
to int automatically.
Reported by Eduard Guzovsky <eguzovsk@enterasys.com>.
* docs/grub.texi (Invoking grub-md5-crypt): Fixed the chapter
name.
Reported by Martin Pool <mbp@sourcefrog.net>.
* configure.ac (STAGE2_CFLAGS): Check if -fno-stack-protector is
supported by GCC. If yes, added the option. This is necessary
for OpenBSD, because the stack protector defines additional
symbols. Reported by uc.sheda <uc.sheda@laposte.net>.
* stage2/char_io.c [!GRUB_UTIL] (memcpy): New function. It is
defined as an alias of grub_memmove. This is copied from GRUB 2.
* stage2/disk_io.c (print_completions): Simplified conditionals
to make it easier to edit the file with Emacs.
Added support for (cd).
(set_device): Likewise.
* stage2/common.c (init_bios_info): Check if BOOT_DRIVE is a
CDROM drive. If it is true, set CDROM_DRIVE to BOOT_DRIVE.
(cdrom_drive): New variable.

Change the type of BUFADDR from int to char *.

buffer.

a bios drive for a CD-ROM is often assigned to greater than
0x88.
(set_device): Use GRUB_INVALID_DRIVE instead of 0xFF.
(setup_part): Likewise.
* stage2/cmdline.c (init_cmdline): Use GRUB_INVALID_DRIVE.

* stage2/bios.c (biosdisk): Don't fall back to the CHS mode
if the drive is a CDROM.
(get_cdinfo): New function.
(get_diskinfo): Call get_cdinfo if the drive is greater than or
equal to 0x88 or the drive supports LBA.
Set the sector size to SECTOR_SIZE if it is not a CD-ROM.
* stage2/asm.S (biosdisk_int13_extensions): Take a word
argument AX instead of a byte argument AH.
(get_diskinfo_int13_extensions): Removed.
* stage2/Makefile.am (noinst_HEADERS): Added iso9660.h.
(libgrub_a_SOURCES): Added fsys_iso9660.c.

From Boji Tony Kannanthanam <boji.t.kannanthanam@intel.com>:
* util/grub-install.in (convert): Add support for ATARAID
device names.
* lib/device.c (get_ataraid_disk_name) [__linux__]: New
function.
(init_device_map) [__linux__]: Probe ATARAID disks.
* stage2/size_test (check): Don't use the local statement any
longer. It was unneeded actually. Reported by Paul Jarc.
From Sergey Matveychuk <sem@ciam.ru>:
* lib/device.c (get_drive_geometry): Do not open the same device
more than once unnecessarily.
(get_drive_geometry) [__FreeBSD_version >= 500040]: Use new
ioctl methods.
(get_floppy_disk_name) [__FreeBSD__ >= 4]: Use /dev/fd%d rather

* docs/grub.texi (Installing GRUB using grub-install): Added an
example of using grub-install without parentheses.

checking if the grub shell is present. This is necessary to
support options to the grub shell (e.g. grub --read-only).
From Eric Kvaalen <E_Kvaalen.Arnesen@noos.fr>:
* docs/grub.texi: Many bug fixes.
* stage2/terminfo.c (ti_set_term): Use a pointer to struct
terminfo instead to avoid GCC's bug, which inserts a reference
to memcpy implicitly.

All callers are fixed.
* stage2/terminfo.h (ti_set_term): Updated.
(ti_get_term): Likewise.
* stage2/shared.h (struct linux_kernel_header): New member,
initrd_max_address. Defined in the boot protocol 2.03 or higher.
