[PATCH 2.5.66-ac2] PC-9800 sub architecture support (9/9) SCSI

[Osamu Tomita <tomita@cinet.co.jp>]

This is the patch to support NEC PC-9800 subarchitecture
against 2.5.66-ac2. (9/9)

SCSI host adapter support.
 - Override BIOS parameter for PC98.

I rewrite this patch. Function for PC-98 BIOS parameter is called from each
low level drivers. How about this patch. We need PC-98's BIOS parameter to
create bootable partition. Please apply.

Regards,
Osamu Tomita
