EISA(4)                 NetBSD Kernel Interfaces Manual                EISA(4)

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) documen-
     tation 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 man-
     ual pages for each individual driver also lists the supported bus vari-
     ants.
