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) documentation 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 Ethernet 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 manual pages for each individual driver also lists the supported bus variants.
