Hi all.  Much progress has been made on the Sun2 port.  It now boots
multiuser, a snapshot of programs run, and I've developed a driver for
the 'sc' SCSI board that seems to work pretty well.

Thanks go to Michael Thompson for helping me test all of this!

Should I post the sc driver somewhere?  I'd say that it's slightly
better than alpha quality, I still wouldn't trust it with critical
data.  It does DMA and I haven't had any problems with it yet tho.

I modelled it after the si driver in that it's broken up into
sc_<bus>.c and sc.c under arch/sun3/dev, and an MI sunscpal.c under
dev/ic.  (And "modelled" is misleading - all of the 'sc' and
'sunscpal' files are literally modified copies of the si and
ncr5380sbc files.  Much credit goes to those authors.)  I wrote an
sc_vme attachment but I have no idea if it works since I don't have
any VME hardware.

A multiuser session transcript follows.  Note that the kernel booted
from /dev/sd0a using the NetBSD boot blocks.  I would have root on sd0
if the disk were only big enough! :)

Matt
