There was a problem with FreeBSD; the SCSI driver would only work with
at least revision 'A' of the WD33C93 chip. Plus it didn't use DMA.

NetBSD/mvme68k now has a proper SCSI driver which supports DMA. I ported
the original driver (based on the NetBSD/amiga driver) a few months ago
to NetBSD-1.1, and it is now in the NetBSD-current tree. The driver has
been tested by a few people besides myself, and I've not yet had any
negative feedback.

The only drawback, if you can call it one, is that you need to have
NetBSD/mvme68k running in the first place to 'newfs' a SCSI partition...
I had to do this by installing NetBSD/i386 on a PC and using that as
an NFS server to the '147.

I suppose the other problem is that Chuck Cranor (mvme68k maintainer)
hasn't yet packaged up a snapshot with the SCSI driver. (At least not
that I'm aware of.)

If you want to discuss any way around these problems, email me.

Cheers, Steve
