# 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(4)
  Compaq array controllers.
mlx(4)
  Mylex DAC960 and DEC SWXCR RAID controllers.

## SCSI interfaces

ahb(4)
  Adaptec 174x SCSI interfaces.
ahc(4)
  Adaptec AIC 7770, 274x, and 284x SCSI interfaces.
bha(4)
  BusLogic BT-74x SCSI interfaces.
dpt(4)
  DPT SmartCache/SmartRAID III and IV SCSI interfaces.
uha(4)
  Ultrastor 24f SCSI interfaces.

## Network interfaces

ep(4)
  3Com 3c579 and 3c592 10Mbit Ethernet, and 3c597 10/100Mbit Ethernet interfaces.
le(4)
  Digital DE422 Ethernet interfaces.
tlp(4)
  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.
