[comp.unix.xenix] Adaptec AHA-1542A floppy/SCSI controller technical info needed

dyer@spdcc.COM (Steve Dyer) (04/06/89)

The AHA-1542A is identical to the AHA-1540A AT-bus SCSI controller, except that
it also contains a floppy controller (presumably with the same interface
as the IBM AT floppy/hard disk controller, though I can't be sure.)
However, the AHA-1540A is on some sort of manufacturing hold until the
end of April, and I needed it sooner.  The 1542A board arrived today, sans
any manual or documentation, which should be remedied once I phone and
charbroil the salesman for shipping it to me without such.  However, I'd
like to get started NOW, so I have a question, if any of you might know
the answer...

My application really only needs the SCSI controller, and I'd like to
disable the floppy interface if at all possible to avoid conflicts with
an existing floppy/ST506 controller.  Is anyone out there familiar with
the 1542A board or has the documentation on hand who can tell me whether
this is possible, and if so, how?

Thanks,

Steve Dyer
