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

	* docs/grub.texi (FAQ): Removed. See the GNU GRUB FAQ on the web
	instead.
	
2002-05-31  Yoshinori K. Okuji  <[e-mail]>

	* docs/grub.texi (Reporting bugs): Recommend using the BTS on

2002-05-25  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c (boot_func): Load the boot partition
	information, only if the address of the boot partition entry is
	set appropriately.
	(real_root_func): If ATTEMPT_MOUNT is false, call open_partition
	and if successful, call set_bootdev, to set the offset of the
	boot partition and the address of the boot paetition entry.

	is useless with the command "rootnoverify" anyway.
	* stage2/disk_io.c (boot_part_addr): Initialized with zero
	explicitly, to emphasize that it is invalid.
	
2002-05-24  Yoshinori K. Okuji  <[e-mail]>

2002-05-23  Yoshinori K. Okuji  <[e-mail]>

	* configure.in (AM_INIT_AUTOMAKE): Changed the version number to
	0.93.
	
2002-05-23  Yoshinori K. Okuji  <[e-mail]>

	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 <[e-mail]>.
	
	* 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.
	
2002-05-22  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c (boot_func): If DEBUG is true, print
	BOOT_DRIVE and BOOT_PART_OFFSET.
	Don't set ERRNUM after rawread failed, because rawread should
	set ERRNUM itself.
	
2002-05-20  Yoshinori K. Okuji  <[e-mail]>

	* lib/device.c (read_device_map): Show an error message and exit
	abnormally, if MAP[DRIVE] has already been filled.
	* util/grub-install.in: If there is any dulicated entry, print
	an error message and exit abnormally.
	
2002-05-20  Yoshinori K. Okuji  <[e-mail]>

	* lib/device.c: Don't include linux/hdreg.h, linux/major.h,
	or linux/kdev_t.h.
	[__linux__] (HDIO_GETGEO): Defined.
	[__linux__] (hd_geometry): Likewise.
	[__linux__] (FLOPPY_MAJOR): Likewise.
	[__linux__] (MINORBITS): Likewise.
	[__linux__] (MAJOR): Likewise.
	
2002-05-08  Yoshinori K. Okuji  <[e-mail]>

	* netboot/fsys_tftp.c (tftp_read): Don't call buf_fill unless
	SIZE is positive.
	
2002-05-08  Yoshinori K. Okuji  <[e-mail]>

	* netboot/etherboot.h (ETH_MAX_MTU): Because some DHCP/BOOTP
	servers don't treat the maximum length the same as Etherboot,
	subtract the size of an IP header and that of an UDP header.
	
2002-04-30  Yoshinori K. Okuji  <[e-mail]>

	From Jean-Jacques Michel <[e-mail]>:
	* stage2/boot.c (load_image): For Linux, check if DATA_LEN is
	greater than MULTIBOOT_SEARCH. If that's true, read the rest
	after copying data already read in BUFFER.
	
2002-04-30  Yoshinori K. Okuji  <[e-mail]>

	* stage2/boot.c (load_image): For Linux, don't check if the
	length of protected mode code is greater than or equal to the
	expected length minus 16. Instead, just check if no error
	occurred. That was problematic, because memdisk has no protected
	mode code. Also, I don't see what the magic number 16 was for.
	
2002-04-29  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c [SUPPORT_SERIAL] (terminal_func): Added a
	new option ``--silent''. This suppresses messages, if specified.

2002-04-17  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c [SUPPORT_SERIAL] (terminal_func): Set
	COUNT_LINES to -1, to disable the pager.
	
2002-04-16  Yoshinori K. Okuji  <[e-mail]>

	to the binutils site.

2002-04-06  Pavel Roskin  <[e-mail]>

	* util/grub-install.in: Fix hardcoded /dev/hda1.

2002-04-06  Yoshinori K. Okuji  <[e-mail]>

	[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.
	
2002-04-04  Yoshinori K. Okuji  <[e-mail]>

	``--lines=LINES''.

	* configure.in (AC_INIT_AUTOMAKE): Set the version number to
	0.92.
	
2002-03-26  Yoshinori K. Okuji  <[e-mail]>

	* netboot/eepro100.c (eepro100_probe): Increase the delay at the
	initialization.
	
2002-03-26  Yoshinori K. Okuji  <[e-mail]>

	* 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.
	* stage2/shared.h (ERR_NUMBER_OVERFLOW): New constant.
	
2002-03-24  Yoshinori K. Okuji  <[e-mail]>

	* stage2/stage2.c (run_menu): Call cls outside the loop to run
	scripts.
	* stage2/cmdline.c (run_script): Prompt a user's intervention,
	only when FALLBACK_ENTRY is negative.
	
2002-02-11  Pavel Roskin  <[e-mail]>

	* util/grub-install.in (find_device): New function - find block
	device for given file or directory.  Resolve symlinks to fix
	problem on Linux with devfs and old device names in /etc/fstab.
	Use find_device() for root_device, bootdir_device and
	grubdir_device.

2002-02-08  Yoshinori K. Okuji  <[e-mail]>

	* grub/main.c (OPT_NO_PAGER): New macro.
	(longopts): Added an entry for "--no-pager".
	(usage): Added a description about "--no-pager".
	(main): In case of OPT_NO_PAGER, set USE_PAGER to zero. The same
	thing is done with OPT_BATCH, because the pager is just harmful
	in batch mode.
	
2002-02-08  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c (help_func): Show all the commands runnable
	with the command-line interface, if "--all" is specified.
	
2002-02-08  Yoshinori K. Okuji  <[e-mail]>

	An internal pager is implemented.
	
	* stage2/builtins.c (pager_func): New function.
	(builtin_pager): New variable.
	(terminal_func): New option, "--lines=LINES" is added. If this
	option is specified, set MAX_LINES to the value. Otherwise, set
	MAX_LINES to 24.
	(vbeprobe_func): Remove the pager code specific to this
	function.
	(builtin_table): Added a pointer to BUILTIN_PAGER.
	* stage2/char_io.c (max_lines) [!STAGE1_5]: New variable.
	(count_lines) [!STAGE1_5]: Likewise.
	(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.
	(use_pager) [!STAGE1_5]: Likewise.
	
2002-02-08  Yoshinori K. Okuji  <[e-mail]>

	* stage2/fsys_jfs.c (jfs_read) [STAGE1_5]: Set and reset
	DISK_READ_FUNC even in Stage 1.5.
	* stage2/fsys_xfs.c (xfs_read) [STAGE1_5]: Likewise.

	* stage2/stage1_5.c (saved_sector): Initialized with -1.
	(cmain): Check if SAVED_SECTOR was set appropriately after
	reading the second sector of Stage 2. If SAVED_SECTOR is not
	set (i.e. it is equal to -1), print an error and stop.
	
2002-02-05  Yoshinori K. Okuji  <[e-mail]>

	* stage2/builtins.c (setup_func): Add a VSTa fs entry into
	STAGE1_5_MAP.
	
2002-02-05  Yoshinori K. Okuji  <[e-mail]>

	* stage2/shared.h (BUILTIN_HELP_LIST): New macro. Used for
	commands whose help messages are listed when no argument is
	specified to the command "help".
	* stage2/builtins.c (builtin_blocklist): Added the attribute
	BUILTIN_HELP_LIST.
	(builtin_boot): Likewise.

	(help_func): When no argument is specified, if the last entry
	was at the left column, print an extra newline.
	
2002-02-05  Yoshinori K. Okuji  <[e-mail]>

	* stage2/shared.h (BUILTIN_HIDDEN): Renamed to ...
	(BUILTIN_NO_ECHO): ... this. The old name was too difficult to
	see _what_ was hidden.
