It mainly controls system devices that aren't shown by the currently
supported buses. These include devices ranging from the pc speaker to
the monitor. I encourage you to try it out. It allows the user to
change the resources used by these devices and provides information for
drivers. It also can be used to enable devices that were disabled by
the BIOS. Here's a list of supported devices. I hope to incorporate
this list into the pnpbios driver in the future.
ID range Category
-------- -------------
PNP0xxx System devices
PNP8xxx Network adapters
PNPAxxx SCSI, proprietary CD adapters
PNPBxxx Sound, video capture, multimedia
PNPCxxx - Dxxx Modems

I fixed the {}. :-) The pnpbios driver only supports dev ids with the
length of 7. Any shorter or longer would be considered invalid by the
PNPBIOS Specifications. Therefore it makes sence to force it to use a
length of 7. Look at the devid list I included.
