tcds —
TURBOchannel dual-channel SCSI adapters
tcds* at tc? slot ? offset ?
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.
