Perhaps he is seeing some unrelated BIOS problem?

I have an old Intel Venus Ppro motherboard that always seems to need
to have the drives rebuilt when I put them in there.  I can't get it
to boot from a transplanted drive with a valid Netbsd bootstrap and
FS.  If bombs out claiming "No OS".  This is even after playing with
the Venus board's BIOS settings for drive access (LBA, C/H/S,
extended, whatever-we-think-of-next) I can only get it to boot a drive
if I actually fdisk/disklabel/install the software from that
motherboard.  All the other motherboards I have aren't that picky.
