NAME
     mca - introduction to machine-independent MCA bus support and drivers

SYNOPSIS
     mca0 at mainbus?

     options MCAVERBOSE

     Machine-dependent; depends on the bus topology and MCA bus interface of
     your system. Typical MCA buses are connected directly to the main system
     bus.

DESCRIPTION
     NetBSD includes a machine-independent MCA bus subsystem and several
     machine-independent MCA device drivers.
