NAME

     tcds -- TURBOchannel dual-channel SCSI adapters


SYNOPSIS

     tcds* at tc? slot ? offset ?


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.
