* grub/main.c (use_preset_menu): New variable.
(OPT_PRESET_MENU): New macro.
(longopts): Added an entry for "--preset-menu".
(usage): Added a description for "--preset-menu". Also, change
the first character of the description for "--device-map" to
lower case for consistency.
(main): Set USE_PRESET_MENU to 1 in the case of OPT_PRESET_MENU.
* stage2/shared.h (use_preset_menu): Declared.
* stage2/stage2.c [PRESET_MENU_STRING || SUPPORT_DISKLESS]
(open_preset_menu) [GRUB_UTIL]: If USE_PRESET_MENU is false,
return zero immediately.
* stage2/common.c [SUPPORT_DISKLESS]
(setup_diskless_environment): Removed. The feature is moved to
the preset menu.
* stage2/stage2.c [SUPPORT_DISKLESS] (preset_menu): Set to the
string "bootp\n".
[SUPPORT_DISKLESS] (preset_menu_offset): Defined, as if
PRESET_MENU_STRING is defined.
[SUPPORT_DISKLESS] (open_preset_menu): Likewise.
[SUPPORT_DISKLESS] (read_from_preset_menu): Likewise.
[SUPPORT_DISKLESS] (close_preset_menu): Likewise.
The preset menu has a priority over the configuration file.
Suggested by Christoph Plattner.
* stage2/stage2.c [PRESET_MENU_STRING] (open_preset_menu):
Check if PRESET_MENU is not NULL.
[PRESET_MENU_STRING] (close_preset_menu): Set PRESET_MENU to
NULL.
(cmain): New internal function, reset. This function resets
AUTO_FILL, CONFIG_LEN, MENU_LEN, NUM_ENTRIES, CONFIG_ENTRIES,
MENU_ENTRIES and call init_config.
Try to open the preset menu first, and try to open the
configuration file, only if that failed.
Even if the preset menu was read, try to open the configuration
file. This time, opening the preset menu never succeed, because
close_preset_menu ensures that the preset menu is available at
most once.
* stage1/stage1.S: Don't call INT 13, AH=48H, because it is
difficult to call this function with the workaround implemented
in the previous change due to the size limit of Stage 1.
(lba_mode) [NO_BUGGY_BIOS_IN_THE_WORLD]: Don't check the
geometry explicitly. This shouldn't be harmful, as INT 13,
AH=42H should take care of it, and if you cannot read Stage 2
even with LBA because of a geometry problem, you can never read
it.
* stage2/start.S (lba_mode) [NO_BUGGY_BIOS_IN_THE_WORLD]:
Likewise.
* stage2/bios.c (get_diskinfo): Clear out the structure DRP
before calling get_diskinfo_int13_extensions, because the Ralf
Brown's Interrupt List says that Dell machines using PhoenixBIOS
4.0 Release 6.0 fail, if DRP.FLAGS is not zero. Setting the
entire structure to zero may be overkill, but it should be safe.
* stage2/char_io.c [STAGE1_5] (grub_memset): Defined.
assignments received by the FSF.
Jason Thomas was added.
Erich Stefan Boleyn was moved into those who assigned their copyrights.
Gordon Matzigkeit was moved into the others, because he still wasn't listed
in fencepost.gnu.org:/gd/gnuorg/copyright.list.
The remaining problem is that we haven't had copyright assignments of
VaX#8, Heiko Schroeder and Gordon Matzigkeit. As for the first two, Erich
is now trying to contact them by proxy. So I'm just waiting.
As for Gordon.... oh, what are you doing, Gordon?! Hurry up, please!
to better match recent reiserfs versions.
(reiserfs_mount): Handle cases where journal can't be found,
e.g. journal on another disk or unexpected journal parameters.
In that case the journal isn't used.
the superblock field s_journal_block_count anymore. It used
to contain 0, it never contained a valid value, and now I
have a report that it can contain an invalid value.
