Don't save/restore fragile registers unnecessarily.
* stage2/asm.S [!STAGE1_5] (track_int13): Don't save/restore
%ecx, %edx, or %eax.
[!STAGE1_5] (set_int13_handler): Likewise.
(biosdisk_int13_extensions): Likewise.
(biosdisk_standard): Likewise.
(check_int13_extensions): Likewise.
(get_diskinfo_int13_extensions): Likewise.
(get_diskinfo_standard): Likewise.
(get_diskinfo_floppy): Likewise.
[!STAGE1_5] (get_eisamemsize): Likewise.
[!STAGE1_5] (get_mmap_entry): Likewise.
[!STAGE1_5] (console_cls): Likewise.
[!STAGE1_5] (nocursor): Likewise.
[!STAGE1_5] (console_getxy): Likewise.
[!STAGE1_5] (console_gotoxy): Likewise.
[!STAGE1_5] (set_attrib): Likewise.
[!STAGE1_5] (getrtsecs): Likewise.
[!STAGE1_5] (currticks): Likewise, and don't zero %eax
explicitly, since prot_to_real does that.

* stage2/char_io.c [!STAGE1_5] (translate_keycode): New
function. The serial part is stolen from the patch by Christoph
Plattner.
[!STAGE1_5] (get_cmdline): Call translate_keycode instead of
translating special key codes into ASCII characters by itself.
* stage2/stage2.c (run_menu): Wrap getkey with the macro
ASCII_CHAR, when checking if ESC is pressed.
Call translate_keycode as well as getkey, unless checkkey
returns -1. So don't check if C is KEY_DOWN or KEY_UP. And don't
use the macro ASCII_CHAR for C explicitly.
* stage2/shared.h (translate_keycode): Declared.
2000-08-24 OKUJI Yoshinori <okuji@gnu.org>
* stage2/builtins.c [GRUB_UTIL]: Include stdio.h before
