Theres several BIOS bugs where registers and segments arent the way
they're supposed to. I don't know if this is an issue, but its one
thing to keep a lookout for. Another might be to use the BIOS in
general a bit more extensively, even though its easier not to use it
quite often.

The bootsector I wrote for retroforth will boot on pretty much any 386
PC, I believe, as long as the floppy drive works.
