I want to use Mach on a Pentium PC with NCR53C810 PCI SCSI controller.
I grabbed your source and found what I think is a driver for the 
NCR53C700 under mach4/mach4-parisc/kernel/hpsgc/scsi_ncr53c700.c.
I heared that the 53c810 essentially supports a superset of the 53c700
SCRIPTS commands. Would that indicate that I could use the 5xc700
driver for the 53c810?

Who wrote that driver (HP themselves?)?

Why does the driver live under the mach4-parisc hierarchy?
The normal place would seem to be mach4/mach4/kernel/scsi/adapters?!

Can I just rip out the scsi_ncr53c700.{c,script} and use them for the
PC port?

Where should I place them? 

What else would I need?

Should I rather try to use the 53c810 driver for NetBSD/FreeBSD?

Any other comments?
