SCSI BIOS not loading

I have a SuperMicro 370SSA motherboard that won’t recognize the Adaptec 3940UW SCSI controller. I have moved it to 3 different slots to no avail. The system only has SCSI hard drives and there is no option to select SCSI as a boot device in the BIOS. The SCSI BIOS doesn’t even load. Do I have a bad board? Please help. Thanks!
