Serial/Parallel Port Configuration Submenu of the Advanced Menu
The Serial/Parallel Port Configuration submenu provides the ability to set the I/O addresses and interrupt levels for the serial, infrared, and parallel ports of your notebook.
P O I N T
To prevent IRQ and address conflicts, avoid changing the default settings. If you must change the settings, you can call 
 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.

The BIOS will warn you of a resource conflict by placing a yellow asterisk next to each device that is in conflict.

All I/O addresses in Table 5 are in hexadecimal.
