Subject[PATCH] PC-9800 subarch. support for 2.5.64-ac3 (11/20) NIC
This is the patch to support NEC PC-9800 subarchitecture
against 2.5.64-ac3. (11/20)

C-bus(PC98's legacy bus like ISA) network cards support.
Change IO port and IRQ assign.
Add auto detect function for some cards.
PCI netwwork card works fine without patch.

Regards,
Osamu Tomita
