I've been looking at the NCR SCSI chips and
I have a few questions about them:

What are the major differences between them?
Both the 53c810 and 53c815 are 8 bit SCSI-2 at 10MB/sec
so what's the major difference? Something to do with
the BIOS?

53C810 - fast SCSI2, no BIOS on board.  relies on motherboard with
	SDMS BIOS support for BIOS functions
53C815 - fast SCSI2, SDMS BIOS on board
53C825 - fast wide SCSI2, SDMS BIOS on board

Bingo, the 815 has it's own SDMS-BIOS on board, the 810 requires
support from the main BIOS.
