SETPNP(8) System Manager's Manual SETPNP(8)NAME
setpnp - modify Plug and Play BIOS device resources
SYNOPSIS
setpnp [-b] device resource...
setpnp [-b] device {on|off}
DESCRIPTION
This utility updates the system resource information for Plug and Play BIOS device nodes. A device is specified by its two-digit hex node
number. In its first form, a list of resources are given on the command line. Alternatively, a device can either be simply switched
``on'' (reset to its boot configuration) or ``off'' (all resources disabled).
There are four types of resources: ``io'', ``mem'', ``irq'', and ``dma''. A resource list consists of one or more space-separated pairs of
a resource type with one or more values. Multiple values for one resource type can be separated by commas. Values can also either be uni-
tary or dash-separated ranges. For example:
setpnp 0d io 0x2f8-0x2ff irq 3
setpnp 12 io 0x350-0x35f,0x2f8-0x2ff irq 3 irq 10
setpnp 0b irq off
The order of items of different types is not important, but if more than one item of the same type is present, their relative order is sig-
nificant. The Plug and Play BIOS will reject invalid configuration attempts; however, setpnp will not attempt to determine why a configu-
ration was rejected.
By default, current (dynamic) device configuration information is modified. With the -b option, a device's boot (static) configuration can
be updated. Some devices may only be reconfigured for the following boot. Be especially careful when modifying your system's boot config-
uration. Improper use of this command may disable vital system devices and render your system unbootable.
OPTIONS -b Boot mode: update the device resource information that will be used at next boot (as opposed to current resource info).

pnpbios -- support for embedded devices on the motherboard
DESCRIPTION
The pnpbios driver enumerates embedded ISA devices on the motherboard whose BIOS supports ``Plug and Play BIOS Specification''. It assigns
ISA bus resources (interrupt line, DMA channel, I/O ports, and memory region) to each device and activates it.
If it cannot assign necessary resources to a device without causing conflict with other devices in the system, the device will not be acti-
vated and will be unavailable to programs.
CAVEATS
There is no explicit way to disable individual embedded devices. The pnpbios driver will find all devices reported by the ``Plug and Play
(PnP)'' BIOS and try to activate them all.
There is no way to explicitly assign particular resource to a device. The resource assignment is fully automatic and there is no provision
for manual override.
