1999-11-06 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>
* grub/asmstub.c (grub_putchar) [HAVE_LIBCURSES]: Do not call
wrefresh. This was just an accident. Sorry.
Reported by Alan McLean <amcl@flash.net>:
* stage2/builtins.c (embed_func): The sector argument for the
function biosdisk is changed from SECTOR + I * SECTOR_SIZE to
SECTOR + I.
(find_func): Clear ERRNUM before each of the attempts.

* docs/multiboot.texi (Boot information format): Add the members
