2.6 install - no disk drive options

[B <grisinge_(_at_)_cs_(_dot_)_colostate_(_dot_)_edu>]

Apologies if this has been covered, I couldn't find it in the archives.
I have a Compaq Deskpro XL from a few years back.  Currently it boots 
SUSE Linux off of a scsii hard drive connected to an Adaptec 1542CF 
card.  The card is bootable (obviously). The onboard scsii controller 
is an AMD that basically nothing supports.  I would really like to 
run OpenBSD on this machine.  I have the CDs and made a boot floppy. 
(The CD is connected to the same scsii card - the Adaptec)  My woe is 
this, the installer starts but can never find the hard drive.  When 
it gets to the point where it asks where I want to put the root 
partition, there are no options.  I have gotten the same results with 
both copies of the boot floppy image.  Is there a quick and dirty 
thing I can do to make BSD see the drive, or should I send along a 
list of all of the fun blue writings at the beginning?

As far as the Adaptec, it is set to -enable sync negotiation
                                    -enable fast SCSI
                                    -enable Disconnection
                                    -Send Start Unit Command
                                    -Include in BIOS Scan
for the hard drive.  My thought is that one or a combination of these 
settings may not jive with OpenBSD, but fiddling with them did not 
seem to work - but I may have missed a combination.

Thanks for any help.
