is driven by the asc(4) driver. The PMAZ-FS (Alpha onboard only) and PMAZC-AA (option board) provide two Fast Narrow SCSI busses, while the
PMAX-DS (Alpha onboard only) and PMAZB-AA only provide Narrow SCSI. For the onboard Alpha controllers, one bus is for internal devices and
one bus for external devices.
