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.

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.
