	* grub/asmstub.c (console_translate_key): Deal with KEY_PPAGE

	`-malign-jumps', `-malign-loops' and `-malign-functions',
	because `-malign-*' are obsolete in GCC 3.x. Reported by Jeremy
	Katz.

2002-09-13  Yoshinori K. Okuji  <[e-mail]>

	* stage2/serial.c (fill_input_buf): Take a new argument NOWAIT.

2002-07-12  Yoshinori K. Okuji  <[e-mail]>

	* 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.

	* stage2/shared.h (boot_part_offset): Removed.
	
	* stage2/disk_io.c (set_bootdev): Copy the partition information
	here. Now this function can call rawread, so it can fail.

	* stage2/builtins.c (boot_func): Don't copy the partition
	information here.
	(real_root_func): Check ERRNUM after calling set_bootdev.

2002-07-04  Yoshinori K. Okuji  <[e-mail]>

	* docs/grub.texi (Reporting bugs): Use the group name (i.e.
	grub) instead of the group id (i.e. 68) for the URL of the BTS.

2002-07-03  Yoshinori K. Okuji  <[e-mail]>

	* stage2/serial.c [!GRUB_UTIL] (serial_hw_fetch): Fixed a typo.

	(terminal_func): Set CURRENT_TERM to each of selected terminals
	before calling grub_printf, and restore CURRENT_TERM after it.
	Reported by Ilguiz Latypov.

	is ugly that the same messages fulfill the whole screen.

2002-06-30  Yoshinori K. Okuji  <[e-mail]>

	* stage2/serial.c [!GRUB_UTIL] (serial_hw_fetch): Fixed the
	conditional statement. Reported by Ilguiz Latypov.
	
2002-06-24  Yoshinori K. Okuji  <[e-mail]>

	roll, because 386 doesn't have bswap. Reported by Frode Vatvedt
	Fjeld <[e-mail]>.
	
2002-06-12  Yoshinori K. Okuji  <[e-mail]>

	* netboot/main.c (ifconfig): If GW is specified, clear out the

2002-06-12  Yoshinori K. Okuji  <[e-mail]>

	* util/grub-md5-crypt.in: Prompt to retype a password, and check
	if the passwords matches. Suggested by Matt Perry
	<[e-mail]>.
	Also, don't use Perl any longer, because *BSD's sh and GNU
	support ``read -r'', and GRUB doesn't support any other
	operating system anyway.
