I/O Device Configuration Menu
The CPU communicates with external devices such as printers through devices called
In-
put/Output (I/O) ports
such as serial and parallel 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 require manually setting them in Setup.
On some systems, the
chipset
manages the communication devices. Other systems have, in-
stead, 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. Select "I/O De-
vice Configuration" on the Advanced Menu to display this menu and specify how you want to
configure these I/O Devices:
