Figure 7.11. IO Features Window (Factory Settings)
The CPU communicates with external devices such as printers through devices called Input/Output (I/O)
ports such as serial and parallel ports. Theses 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, instead, a
separate I/O chip on the CPU board for configuring and managing these devices.
Use the following chart to configure the Input/Output settings:
