ISAPNP(4)

NAME
isapnp - introduction to ISA Plug-and-Play support

SYNOPSIS
isapnp0 at isa?

An
isapnp bus can be configured for each supported ISA bus.

INTRODUCTION
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:

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

  Network interfaces
ep  3com 3c509B Etherlink-III Ethernet interface.
le  PCnet-PnP ethernet interfaces based on the successor to the AMD LANCE chip.

  Sound cards
sb  Soundblaster, Soundblaster 16, and Soundblaster Pro sound cards.
guspnp
    Gravis Ultrasound PnP sound cards.

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 device 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.
