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.

NAME

     tc -- TURBOchannel expansion bus driver

SYNOPSIS

   alpha
     tc* at tcasic?

   pmax
     tc* at mainbus0

DESCRIPTION

     The tc driver provides machine-independent support for the DEC TURBOchannel expansion bus found on all DEC 5000-series machines with MIPS and
     DEC 3000-series with Alpha processors.

     Your system may support additional TURBOchannel devices.  Drivers for TURBOchannel devices not listed here are machine-dependent.	Consult
     your system's intro(4) for additional information.

HISTORY

     The tc driver first appeared in NetBSD 1.1.

BUGS

     The tc driver makes poor use of interrupt priority on the 5000/1xx series systems.
