Serial/Parallel Port Configuration Submenu of the Advanced Menu
The Serial/Parallel Port Configuration submenu lets you set the I/O addresses and interrupt 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, serial or parallel, have the same address assigned, your notebook will not function normally. Keep a record of original settings before making any changes if restoration is required. See your hardware and software documentation as well as the setup utility to determine settings and limitations.
■To prevent IRQ and address conflicts, avoid changing the default settings. If you must change the settings, you can call 
■If your notebook emits a series of beeps that sounds like a code and the display is blank, refer to the Troubleshooting Sec- tion in the system User’s Guide. The Troubleshooting Section includes a list of error messages and their meanings.
■All I/O addresses in Table 5 are in hexa- decimal.
