Adaptec AIC-7880 SCSI Adapter

["Christopher M. Terry" <cterry@cs.ua.edu>]

I have recently been attempting to install OpenBSD on an IBM PC Server 325
which uses an Adaptec AIC-7880 SCSI Adapter.  Although it seems that the OS
detects and uses the adapter correctly during installation, the machine
hangs after printing "Using Drive:  0 Partition:  3" on reboot.  However, if
I boot from a floppy and mount sd0a, the contents of the drive appear to be
fine.

I have tried this with both version 2.3 (on CD) and a downloaded copy of
version 2.4.  The machine previously had Linux v4.? running on it.  The SCSI
settings have not changed from the previous installation so the boot
sequence is fine.

I did note that the Adaptec 78x adapters were not listed on the CD insert as
being supported.  Is this the crux of my problem?
