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
	   aha	    Adaptec AHA-1640 SCSI interface

	   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.

   Network interfaces
	   tr	    TROPIC based token ring interfaces

	   ate	    Allied-Telesis 1720 Ethernet interface cards

	   we	    WD/SMC WD80x3x Ethernet interface cards and clones

	   le	    SKNET Personal and MC+ Ethernet interface cards

	   elmc	    3Com EtherLink/MC (3c523) Ethernet interface

	   ep	    3Com EtherLink III 3c529 Ethernet interface
