2000-08-27 OKUJI Yoshinori <okuji@gnu.org>
Preserve a magic number used by Windows NT in a MBR. Shit!
Reported by Khimenko Victor.
* stage1/stage1.h (STAGE1_WINDOWS_NT_MAGIC): New macro.
* stage1/stage1.S (copy_buffer): Use pusha and popa, instead of
pushing/poping %cx and %si separately, to reduce the code size.
(nt_magic): New label. Set the offset to _start plus
STAGE1_WINDOWS_NT_MAGIC
(part_start): New label.
* stage2/builtins.c (install_func): If DEST_DRIVE is a hard
disk, copy the possible partition table and Windows NT magic to
STAGE1_BUFFER from OLD_SECT.

* stage2/char_io.c (translate_keycode) [SUPPORT_SERIAL]: Don't
drain the input buffer, since that was irritating.

Don't save/restore fragile registers unnecessarily.
