TC(4)                        Device Drivers Manual                       TC(4)

NAME
     tc - TURBOchannel expansion bus driver

SYNOPSIS
   alpha
     tc* at tcasic?

   pmax
     tc* at mainbus0

   vax
     tc0 at vsbus0

DESCRIPTION
     The tc driver provides machine-independent support for the DEC
     TURBOchannel expansion bus found on all DEC 5000-series machines with
     MIPS, DEC 3000-series with Alpha processors and VAXstation 4000 machines
     with the optional TURBOchannel adaptor.

     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

                      SCSI adapters

   Network interfaces
           le(4)      LANCE Ethernet interface

   Frame buffers
           cfb(4)     PMAG-B CX colour unaccelerated 2-D framebuffer

           mfb(4)     PMAG-A MX monochrome framebuffer

           px(4)      PMAG-C PX accelerated graphics boards

           pxg(4)     PMAG-D, PMAG-E and PMAG-F PXG accelerated graphics
                      boards

           sfb(4)     PMAGB-BA HX colour unaccelerated 2-D framebuffer

           tfb(4)     PMAG-J TX 24-bit colour unaccelerated 2-D framebuffer

   Miscellaneous
           ioasic(4)  baseboard IO control ASIC for DEC TURBOchannel systems

           tcu(4)     TC-USB USB host and GPIO option

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.
