Resource Conflicts
Devices within or connected to the computer may require dedicated memory
spaces, interrupt levels, and/or DMA channels. Because different devices can be
configured at different times, it is possible that the same resource is assigned to
two or more devices.
Disconnect all peripherals and remove all PC Cards to make sure that the com-
puter failure is not caused by faulty devices.
