I/O Device Configuration Menu
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:
