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 inter- rupt levels for the serial (infrared) and parallel ports of your notebook.
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 have the same I/O address assigned, your notebook will not function normally.
•To prevent IRQ and address conflicts, avoid changing the default settings. If you must change the settings, you can call
•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.
