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.

HARDWARE
     NetBSD includes machine-independent TURBOchannel drivers, sorted by device type and driver name:

   SCSI interfaces
	   asc	      PMAZ-A single-channel SCSI adapter

	   tcds       PMAZ-DS, PMAZ-FS, PMAZB-AA and PMAZC-AA dual-channel SCSI adapters

   Network interfaces
	   fta	      PMAF-F DEFTA FDDI controller

	   le	      LANCE Ethernet interface

   Frame buffers
	   cfb	      PMAG-B CX colour unaccelerated 2-D framebuffer

	   mfb	      PMAG-A MX monochrome framebuffer

	   px	      PMAG-C PX accelerated graphics boards

	   pxg	      PMAG-D, PMAG-E and PMAG-F PXG accelerated graphics boards

	   sfb	      PMAGB-BA HX colour unaccelerated 2-D framebuffer

	   tfb	      PMAG-J TX 24-bit colour unaccelerated 2-D framebuffer

   Miscellaneous
	   ioasic     baseboard IO control ASIC for DEC TURBOchannel systems

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.
