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
There are four types of resources: ``io'', ``mem'', ``irq'', and

devices may only be reconfigured for the following boot. Be especially
careful when modifying your system's boot configuration. Improper use
of this command may disable vital system devices and render your
Boot mode: update the device resource information that will be used at
next boot (as opposed to current resource info).
