RHL 7.3: grub-0.91-4
RHL 9:   grub-0.93-6

And surprise, the stage1 code is exactly the same.

It prints "GRUB ", then does a few BIOS software interrupt calls to
look whether LBA is supported, else falls back to CHS scheme. It
also contains a bit of floppy probing code. If it doesn't print
anything else than GRUB, it assumes it has loaded the next stage and
executes it.

A bit more sane code (if space permits) would print a few dots right
before executing the next stage or would even verify whether the
loaded next stage starts with a proper signature.

Open questions:

 - is BIOS set to LBA?
 - does grub-install with --force-lba work?
 - does LILO work?
