EISA(4)                  BSD Kernel Interfaces Manual                  EISA(4)

NAME
     eisa -- introduction to EISA bus support

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

     OpenBSD provides support for the following devices.  Note that not all
     architectures support all devices.

   Disk and tape controllers
        cac(4)        Compaq Smart ARRAY 2/3/4 SCSI RAID controller
        dpt(4)        DPT EATA SCSI RAID controller

   SCSI interfaces
        ahb(4)        Adaptec 1742 SCSI interface
        ahc(4)        Adaptec VL/EISA/PCI SCSI interface
        bha(4)        Buslogic SCSI interface
        uha(4)        Ultrastor SCSI interface

   Network interfaces
        ep(4)         3Com EtherLink III and Fast EtherLink III 10/100 Ether-
                      net device

     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.
