NAME

     eisa -- Introduction to EISA bus machine-independent drivers and support

SYNOPSIS

     options EISAVERBOSE

     Machine-dependent; depends on the bus topology and EISA bus interface of your system.  Typical EISA buses are either connected directly to
     the main system bus, or via an PCI to EISA bridge.  See the intro(4) documentation for your system for details.

DESCRIPTION

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

     Your system may support additional EISA devices.  Drivers for EISA devices not listed here are machine-dependent.	Consult your system's
     intro(4) for additional information.

SUPPORTED DEVICES

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

   Disk and tape controllers
	   cac	      Compaq array controllers.

	   mlx	      Mylex DAC960 and DEC SWXCR RAID controllers.

   SCSI interfaces
	   ahb	      Adaptec 174x SCSI interfaces.

	   ahc	      Adaptec AIC 7770, 274x, and 284x SCSI interfaces.

	   bha	      BusLogic BT-74x SCSI interfaces.

	   dpt	      DPT SmartCache/SmartRAID III and IV SCSI interfaces.

	   uha	      Ultrastor 24f SCSI interfaces.

   Network interfaces
	   ep	      3Com 3c579 and 3c592 10Mbit Ethernet, and 3c597 10/100Mbit Ethernet interfaces.

	   fea	      Digital DEFEA FDDI interfaces.

	   le	      Digital DE422 Ethernet interfaces.

	   tlp	      Digital DE425 Ethernet interfaces.

     Note that most or all EISA devices also have PCI or ISA equivalents.  These are listed in pci(4), isa(4), or isapnp(4), respectively.  The
     manual pages for each individual driver also lists the supported bus variants.
