Subject[PATCH] PC-9800 subarch. support for 2.5.62-AC1 (16/21) SCSI
This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.62-ac1. (16/21)

SCSI host adapter support.
- BIOS parameter change for PC98.
- Add pc980155 driver for old PC98.
- wd33c93.c compile fix.

Regards,
Osamu Tomita
