WARNING  Incorrect settings can cause your system to malfunction.  To correct mistakes, return to 
Setup and restore the Setup Defaults by pressing F9.

The CPU communicates with external devices such as printers through devices called Input/Output 
(I/O) ports such as serial ports.  These I/O devices require the use of system resources such as I/O 
addresses and interrupt lines.  If these devices are Plug and Play, either the BIOS can allocate the 
devices during POST, or the operating system can do it.  If the I/O devices are not Plug and Play, they 
may need to be set manually in Setup. 

On some systems, the chipset manages the communication devices.  Other systems have, instead, a 
separate I/O chip on the motherboard for configuring and managing these devices. 

Many systems allow you to control the configuration settings for the I/O ports.  Use this menu to 
specify how the I/O (Input and Output) ports are configured:
