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