A few weeks ago someone at uport told me that a SCSI driver
was in beta test and asked me if I wanted a copy.  Unfortunately,
I wasn't ready for it and said so.  I can't recall which controller
they were testing with (I might have it written down somewhere).

Mylex has a nifty SCSI board that sits on the 32-bit bus and,
in principal, should be faster than anyone else as a result.
They are working on unix drivers (using 386-ix as a testbed,
but expecting that the resulting driver may work with other
386 unix's as well).  The principal limit to such portability 
will be globals shared with other drivers.  The clock driver
is the most likely culprit.  If system calls have been properly
used, perhaps we uport sites can get a SCSI driver without
being exposed to the dread floating point fault, etc.
