Each channel is 43driven by the 44.Xr asc 4 45driver. The PMAZ-FS (Alpha onboard only) and PMAZC-AA (option board) 46provide two Fast Narrow SCSI busses, while the PMAX-DS (Alpha onboard 47only) and PMAZB-AA only provide Narrow SCSI. For the onboard Alpha 48controllers, one bus is for internal devices and one bus for external 49devices. 50.Sh SEE ALSO 51.Xr asc 4 52
