2000-09-06 OKUJI Yoshinori <okuji@gnu.org>
Add support for "boot previously booted entry by default", based
on the patch by Mike Meyer <mwm@mired.org>, but I've modified
his patch thoroughly.
* grub/asmstub.c (saved_entryno): New variable. This is a dummy.
* stage1/stage1.h (COMPAT_VERSION_MINOR): Incremented.
* stage2/asm.S (saved_entryno): New variable.
(codestart) [!SUPPORT_DISKLESS]: Set INSTALL_SECOND_SECTOR to
%ebp. %ebp is set in start.S.
(install_second_sector): New variable.
* stage2/builtins.c (current_entryno): New variable.
(default_func) [!SUPPORT_DISKLESS]: If ARG is "saved", set
DEFAULT_ENTRY to SAVED_ENTRYNO.
(savedefault_func): New function.
(builtin_savedefault): New variable.
(builtin_table): Added a pointer to BUILTIN_SAVEDEFAULT.
* stage2/shared.h (STAGE2_SAVED_ENTRYNO): New macro.
(STAGE2_STAGE2_ID): Changed to 0x10.
(STAGE2_FORCE_LBA): Chaged to 0x11.
(STAGE2_VER_STR_OFFS): Changed to 0x12.
(install_second_sector): Declared.
(saved_entryno): Likewise.
(current_entryno): Likewise.
* stage2/stage2.c (run_menu): Set CURRENT_ENTRYNO to FIRST_ENTRY
+ ENTRYNO, right before calling run_script.
* stage2/start.S (start): Save the sector number of the second
sector in %ebp.
