NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     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    [Toc]    [Back]

     OpenBSD 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    [Toc]    [Back]

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

   Disk and tape controllers    [Toc]    [Back]
        cac(4)        Compaq array controllers.
        dpt(4)        DPT SmartCache/SmartRAID controllers.

   SCSI interfaces    [Toc]    [Back]
        ahb(4)        Adaptec 174x SCSI interfaces.
        ahc(4)        Adaptec AIC 7770, 274x, and 284x  SCSI  interfaces.
        bha(4)        BusLogic BT-74x SCSI interfaces.
        uha(4)        Ultrastor 24f SCSI interfaces.

   Network interfaces    [Toc]    [Back]
        ep(4)          3Com  3c579 and 3c592 10Mbit Ethernet, and
3c597
                      10/100Mbit Ethernet interfaces.
        fea(4)        Digital DEFEA FDDI 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.
