Subject:   Buslogic 445 async only?
Message-ID:  <199510132319.QAA00739@everest>

This has been a problem for quite awhile - and I'd like to get it
resolved now that I have time to look into it.

I have a 486 machine (VL) with a Buslogic 445S and a variety of SCSI-I
and -II disks installed.  On bootup, the kernel reports that the board
is set for async mode.  I don't see anywhere in the docs where this can
be disabled/enabled.  From reading the source, I have learned that the
bt driver only uses what the controller tells it, so it's gotta be an
issue with the controller.

Any ideas?  I'd really like to get this thing working in sync mode.
