PC98 is not an IBM-compatible machine at all.  It is an emulation of a
PC, with a totally different internal architecture.  I think it can
run DOS, or some compatible OS, but everything below DOS is different.
If you look in exceptn.S, you will see that even the BIOS data area
has an entirely different layout, and dpmiexcp.c will show that scan
codes for some keys are different, too.
