These are completely different.  All PC-98 machines don't have "ISA"
devices and buses at all, but a little old PC-AT machines have "ISA"
buses.  And, even if the PC-AT machine does not have "ISA" buses, it
has "PCI-ISA" bridge.

FYI, NetBSD/pc98 has the "systm" virtual bus.

How?

I have had some questions like "Does PC98 have ISA bus?" or "Why PC98
uses ISA driver?".  To clear these questions and problems, I think
that adding separated cbus driver is better way.
