.Sh NAME
.Nm isapnp
.Nd introduction to ISA Plug-and-Play support
.Sh SYNOPSIS
.Cd "isapnp0 at isa?"
.Pp
An
.Nm
bus can be configured for each supported ISA bus.
.Sh DESCRIPTION
.Nx
provides machine-independent bus support and
drivers for ISA Plug-and-Play (isapnp) autoconfiguration of
PnP-compatible
devices on an ISA bus.
.Sh SUPPORTED DEVICES
.Nx
includes machine-independent ISAPNP drivers, sorted by function
and driver name:
.Ss SCSI interfaces

.It sb
SoundBlaster, SoundBlaster 16, and SoundBlaster Pro sound cards.
.It wss
Windows Sound System compatible cards, e.g., most of the cards
with Crystal Semiconductor chips.

.Bl -tag -width pcdisplay -offset indent
.It pcic
.Tn PCI
.Tn PCMCIA

.El
.Pp
ISA Plug-and-Play devices also have alternate ISA drivers with
static ISA IO address configuration.
These are listed in
.Xr isa 4 .
The
.Nm
bus ignores devices that have already been found and configured as
.Xr isa 4
devices.
The
.Nm
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
.Nm
driver also list
the supported front-ends for other buses.
