Most systems require fiddling to even get a drive other than
sd0 and sd1 to be bootable - are you sure this is going to work?
There are only two BIOS vectors AFAIK - 0x80 and 0x81.

Yeah, that's the BIOS alright.  It's saying "I can't read that",
essentially, and is what's happening as the boot blocks try to use
the BIOS to read the kernel off the 3rd drive.

Have you tried booting this by way of OS/2's boot manager rather
than a floppy?  It may have some clever way of reassigning this
since OS/2 seems to boot off your 3rd drive (or does it?  If not then
it's more than possible that this isn't a FreeBSD problem at all
and that NO OS would boot off your 3rd disk).
