I looked around a bit, but couldn't find a driver, but the BBoAW says there's a jumper to enable/disable SCSI, which leads me to believe the driver is memory resident. FindDevice from the IDEFIx package or SCSIInquire from Asim will both show available devices, as will the 3.9 HDToolBox, which is probably more likely to be on your drive already.
Have fun with this board. :-) I've always wanted one. Stuck with Z2 for now.
