     7        * grub/main.c (main): Make sure the boot drive number doesn't
     8        exceed 255.

     35        Fertman <vitaly@namesys.com>.
     36
     372005-09-29  Yoshinori K. Okuji  <okuji@enbug.org>
     38
     39        * docs/multiboot.texi: Fix a bug in the byte order of

     44
     45        * stage2/boot.c (load_image): Even if an OS image is an ELF
     46        object, use the a.out kludge if MULTIBOOT_AOUT_KLUDGE is
     47        specified.
     48
    1492005-05-08  Yoshinori K. Okuji  <okuji@enbug.org>
