# NAME

`isapnp` —
introduction to ISA Plug-and-Play support

# SYNOPSIS

`isapnp0 at isa?`

An

`isapnp` | bus can be configured for each supported ISA bus.

# DESCRIPTION

NetBSD provides machine-independent bus support and drivers for ISA Plug-and-Play (isapnp) autoconfiguration of PnP-compatible devices on an ISA bus.

# SUPPORTED DEVICES

NetBSD includes machine-independent ISAPNP drivers, sorted by function and driver name:

## SCSI interfaces

aha
  Adaptec AHA-154[02] SCSI interfaces.
aic
  Adaptec AHA-1520B SCSI interfaces.

## Disk controllers

wdc
  Standard IDE and ATAPI drive controller.

## Serial and parallel interfaces

com
  8250/16450/16550-compatible ISA PnP serial cards and internal modems.

## Network interfaces

an
  Aironet 4500/4800 and Cisco 340 series 802.11 interfaces.
ep
  3Com 3c509B EtherLink III Ethernet interface.
le
  PCnet-PnP Ethernet interfaces based on the successor to the AMD LANCE chip.
ne
  NE2000-compatible Ethernet interfaces.
tr
  TROPIC based token ring interfaces.

## Sound cards

ess
  ESS Technology derived PnP sound cards and devices.
guspnp
  Gravis Ultrasound PnP sound cards.
sb
  SoundBlaster, SoundBlaster 16, and SoundBlaster Pro sound cards.
wss
  Windows Sound System compatible cards, e.g., most of the cards with Crystal Semiconductor chips.
ym
  Yamaha OPL3-SAx sound cards.

## Miscellaneous devices

pcic
  PCI PCMCIA controllers, including the Cirrus Logic GD6729.

ISA Plug-and-Play devices also have alternate ISA drivers with static ISA IO address configuration. These are listed in isa(4). The `isapnp` bus ignores devices that have already been found and configured as isa(4) devices. The `isapnp` bus is only effective on machines which lack a PnP BIOS, or on which the PnP BIOS has been disabled. The manual pages for each individual `isapnp` driver also list the supported front-ends for other buses.

# HISTORY

The `isapnp` driver appeared in NetBSD 1.3.
