Serial/Parallel Port Configurations Submenu of the Advanced Menu

The Serial/Parallel Port Configurations submenu

provides the ability to set the I/O addresses and

interrupt levels for the serial, infrared and parallel

ports of your notebook.

C A U T I O N

I/O addresses, DMA channels and Interrupt levels

can be entered in various ways, including via the BIOS

setup utility, the control software for the I/O device,

or the hardware. If any two ports or devices, serial or

parallel, have the same I/O address assigned, your

notebook will not function normally. Please keep a

record of original settings before making any changes

in the event that a restoration is required. See your

hardware and software documentation as well as the

setup utility to determine settings, limitations, etc.
