Would you explain how you went into the scsi bios?  Did you have to write
some kind of program for it?  I have a NCR53c810 with Nextor bios
NXT-93BIOS ver1.26M  which has been a pretty much useless controller.
Both NetBSD and Linux will endup getting kernel panics.  I would Like to
know how one could change the scsi bios settings.
