MCA(4)                     Kernel Interfaces Manual                     MCA(4)

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.

HARDWARE
     NetBSD includes machine-independent MCA drivers, sorted by device type
     and driver name:


   SCSI controllers

           esp      NCR 53C90 SCSI Adapter

   Disk and tape controllers
           edc      IBM ESDI Fixed Disk Controller

   Serial interfaces
           com      NS8250-, NS16450-, and NS16550-based serial cards.
