System Resource Specifications - HP EliteBook 8440W Maintenance And Service Manual

System resource specifications

You can use Device Manager to get a graphical view of the system resources that control how the devices work on
the computer. System resources you can access from Device Manager are direct memory access (DMA) channels,
input/output (I/O) ports, interrupt request (IRQ) lines, and memory addresses.
If two devices require the same resource and create a device conflict, you can manually change the resource
settings in Device Manager to be sure each setting is unique.
CAUTION: Improperly changing resource settings can disable your hardware and cause your computer to malfunction or
Ä
become inoperable. Only users who have expert knowledge of computer hardware and hardware configurations should change
resource settings.
