Just like your old CPU board, the AM-137 board has a switch that determines your
primary and secondary boot device. The AM-137’s primary boot switches (switches 1
and 2) are factory configured to boot from a SCSI hard disk drive. The alternate
switches (switches 3 and 4) are configured to
no  alternate device.
The following illustration shows all possible settings for the AM-137’s boot switch:
