ISAPNP(4)                    Device Drivers Manual                   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.

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(4)     Adaptec AHA-154[02] SCSI interfaces.

           aic(4)     Adaptec AHA-1520B SCSI interfaces.

   Disk controllers
           wdc(4)     Standard IDE and ATAPI drive controller.

   Serial and parallel interfaces
           com(4)     8250/16450/16550-compatible ISA PnP serial cards and
                      internal modems.

   Network interfaces
           an(4)      Aironet 4500/4800 and Cisco 340 series 802.11
                      interfaces.

           ep(4)      3Com 3c509B EtherLink III Ethernet interface.

           le(4)      PCnet-PnP Ethernet interfaces based on the successor to
                      the AMD LANCE chip.

           ne(4)      NE2000-compatible Ethernet interfaces.

   Sound cards
           ess(4)     ESS Technology derived PnP sound cards and devices.

           guspnp(4)  Gravis Ultrasound PnP sound cards.

           sb(4)      SoundBlaster, SoundBlaster 16, and SoundBlaster Pro
                      sound cards.

           wss(4)     Windows Sound System compatible cards, e.g., most of the
                      cards with Crystal Semiconductor chips.

           ym(4)      Yamaha OPL3-SAx sound cards.

   Miscellaneous devices
           pcic(4)    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.
