2000-11-22 OKUJI Yoshinori <okuji@gnu.org>
From Vesa Jaaskelainen <jaaskela@tietomyrsky.fi>:
* stage2/builtins.c (testvbe_func): Don't set the bit 14 of a
VBE mode number explicitly when calling get_vbe_mode_info.
(vbeprobe_func): Likewise.
2000-11-22 OKUJI Yoshinori <okuji@gnu.org>
The code for the "INT 13H tracking technique" is somewhat
simplified.
* stage2/asm.S [!STAGE1_5] (track_int13): Don't replace an int13
handler with set_tf_int13_handler. Instead, track_int13 itself
emulates an int13 interrupt.
[!STAGE1_5] (set_tf_int13_handler): Removed.
[!STAGE1_5] (int1_handler): Use movzbw instead of xorb and movb.
2000-11-15 OKUJI Yoshinori <okuji@gnu.org>
* acconfig.h (PRESET_MENU_STRING): New entry.
