TC(4)

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:

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

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.
