	* 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.
	
2002-01-06  Yoshinori K. Okuji  <[e-mail]>

	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.

	* netboot/misc.c (inet_aton): Don't check if *P is an asterisk,

	unknown).

2001-12-30  Yoshinori K. Okuji  <[e-mail]>

	* 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.
	
2001-12-30  Yoshinori K. Okuji  <[e-mail]>

	* 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.
	
2001-12-30  Yoshinori K. Okuji  <[e-mail]>

	From John Goerzen <[e-mail]>:
	* util/grub-install.in (convert): Added NetBSD support.
	
2001-12-30  Yoshinori K. Okuji  <[e-mail]>

	* util/grub-install.in: Set GRUB_PREFIX and BOOTDIR to "/grub"
	and "${rootdir}" respectively in NetBSD.
	
2001-12-30  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c (builtin_geometry): Add extra space
	characters into the long description.
	(builtin_kernel): Likewise.
	(builtin_vbeprobe): Likewise.
	
2001-12-19  Yoshinori K. Okuji  <[e-mail]>

	From Michael Sullivan <[e-mail]>:
	* stage1/stage1.S (real_start): Added a workaround for AST BIOS,
	because it clobbers %dl with INT 13, AH=41H.

2001-12-19  Yoshinori K. Okuji  <[e-mail]>

	* stage2/fsys_fat.c (fat_read): Fix the contradictory comment.
	Reported by Filip Van Raemdonck <[e-mail]>.
	
2001-12-11  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c (displayapm_func): Don't use multi-line
	string literals but string concatenation instead, to suppress
	warnings from gcc-3.0.x.
	* stage2/cmdline.c (print_cmdline_message): Likewise.
	* util/mbchk.c (usage): Likewise.
	
	* stage2/smp-imps.c (imps_read_config_table): Add a break
	statement after the label ``default''.
	
	* util/mbchk.c: Include <stdlib.h> for the prototype of exit.

	* stage2/serial.c (serial_port): Initialize with 0 instead of
	-1, as an invalid value, because SERIAL_PORT is unsigned. This
	change shouldn't affect anything.
	(serial_exists): For the above change, check SERIAL_PORT with 0
	instead of -1.
	
2001-12-10  Yoshinori K. Okuji  <[e-mail]>

	* stage2/shared.h (ERR_NO_DISK_SPACE): New constant.
	* stage2/common.c (err_list): Added an entry for
	ERR_NO_DISK_SPACE.
	* docs/grub.texi (Stage2 errors): Added the description.
	* stage2/builtins.c (embed_func): Use ERR_NO_DISK_SPACE instead
	of ERR_DEV_VALUES when the spare space is too small. Suggested
	by Eric Mumpower <[e-mail]>.
	
2001-12-10  Yoshinori K. Okuji  <[e-mail]>

	* grub/asmstub.c: Include <signal.h>.
	(grub_stage2) [HAVE_LIBCURSES]: If USE_CURSES is true, ignore
	the signal SIGWINCH. Reported by Christian Hudon
	<[e-mail]>.

2001-11-29  Yoshinori K. Okuji  <[e-mail]>

2001-10-10  Jochen Hoenicke  <[e-mail]>

	* stage2/fsys_reiserfs.c (reiserfs_mount):  Don't look at
	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 va
