FYI, I had to apply this cange manually to my prof's R3000. The diff
just didn't line up. I suspect various revisions of this laptop will
have slight differences in the BIOS code. Perhaps one of these will be
accidentally fixed by them....If you really want to fix it, contact
HP/Compaq and tell them that their stuff is broke and they should fix
it.
