Devices within the computer may require dedicated memory spaces, interrupt
levels, or DMA channels, all of which must be allocated during installation of
the devices. Because a device may be installed at a different time, it is possible
that the same resource is assigned to two or more devices.
Resource conflicts can result in disorderly or erratic system operation or failure
of the system to operate at all. If you suspect that resource conflicts might
exist, check the system and reassign the resources as necessary.
