ISAPNP(4) OpenBSD Programmer's Manual ISAPNP(4)NAME
isapnp - introduction to ISA Plug-and-Play support
SYNOPSIS
isapnp0 at isa?
DESCRIPTION
An isapnp bus can be configured for each supported ISA bus.
OpenBSD provides machine-independent bus support and drivers for ISA
Plug-and-Play (isapnp) autoconfiguration of PnP-compatible devices on an
ISA bus.

The isapnp driver appeared in NetBSD 1.3.
CAVEATS
From time to time an isapnp device will be found which the kernel does
not recognize. The kernel matches isapnp devices to device drivers based
on identifiers which each device provides. For example, this device:
joy0 at isapnp0 <Creative SB16 PnP, CTL7001, PNPB02F, Game> port 0x200/8
This joystick calls itself by the two names ``CTL7001'' and ``PNPB02F''.
The latter is a standard name (which the kernel automatically
recognizes), but ``CTL7001'' is a vendor-specific name which needs to be
added to a table. Unfortunately, some devices advertise only their
vendor-specific name; for instance:
isapnp0: <PnP Sound Chip, @P@1001, , > port 0x200/8 not configured
Testing will show that this device is actually a joystick. To resolve
the issue, the actual name ``@P@1001'' has to be entered into the
database found in /sys/dev/isa/pnpdevs and a new kernel must be built.
Then the device will probe like this:
joy0 at isapnp0 <PnP Sound Chip, @P@1001, , > port 0x200/8
