driver provides support for the DEC TURBOchannel PMAZ-DS, PMAZ-FS,
PMAZB-AA and PMAZC-AA dual-channel SCSI adapters. Each channel 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.
