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
SCSI interfaces #
ahc(4)
Adaptec VL/EISA/PCI 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.

HISTORY #
The machine-independent
EISA
subsystem appeared in
OpenBSD 1.2.
