I'm having trouble installing 386bsd with my Adaptec 1742 SCSI
controller.  I have this in an EISA motherboard with an 80486-DX2/66,
and I'm using a Maxtor P1-17S drive with no other devices on the SCSI
bus, on an otherwise minimally-configured system.  I low-level
formatted the disk and have a DOS partition on it that boots normally.

If I set up the controller in 'standard' SCSI mode as if it were a
1542 with the settings as described in the 386bsd installation notes,
it won't boot off the floppy.  It tries to boot, gives me SCSI status
filled with zeros, and then crashes.

If I set up the controller in 'enhanced' SCSI mode it boots without
error messages, but won't let me install because 386bsd doesn't
recognise any hard disk.  Any clues on how to get this up and going?
