NAME

tcTURBOchannel 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.

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.
