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:

Network interfaces

fta

le
LANCE Ethernet interface

Frame buffers

cfb
PMAG-B CX colour unaccelerated 2-D framebuffer

mfb

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

sfb
PMAGB-BA HX colour unaccelerated 2-D framebuffer

tfb

HISTORY

The tc driver first appeared in NetBSD1.1.

BUGS

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