# DESCRIPTION

The `tcds` 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.
