A plan of action The smooth operation of the system depends on the interaction of all devices, programs and features. If the system or one of its attached devices isn't working, resolving the problem can be timeconsuming and frustrating. The recommended procedure for getting multiple devices to work together is to add and configure one device at a time.

If two or more devices use the same IRQ, the processor doesn't know which device is asking for attention. Part I: Getting to Know Your Computer
