NAME

tcTURBOchannel 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.

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.
