9 plan of action

The recommended procedure for getting multiple devices to work
together is to add and set up one device at a time. After you add each
device, test it to make sure it and all previously connected devices work.
The device most recently connected to the system is the one most likely
to be causing a hardware conflict.

Resolving hardware conflicts on your own

Computer components need resources to accomplish a task. A device,
such as a CD-ROM drive or a modem, needs a channel to the computer's

central processing unit (CPU). It also needs a direct channel to the
computer's memory to store information as it works. These channels of
communication are commonly referred to as system resources.

Interrupt request channel

An interrupt request (IRQ) is the channel to the CPU because it interrupts

what the processor is doing and requests some of the processor's time. If
two or more devices use the same IRQ, the processor does not know
which device is asking for attention.
