2.6 Connecting the Ribbon Cables and Wires of
the Ports and Connectors
2.6.1 Serial Ports
The built-in serial ports are RS-
232C asynchronous com-munication
ports with 16C550A-compatible
UARTs that can be used with
modems, serial printers, remote
display terminals, and other serial
devices. You can set the serial ports
I/O address in the Integrated Periph-
erals setup of the Award BIOS.
2.6.2 PS/2 Mouse and Keyboard Ports
The PS/2 mouse port uses IRQ12. If
a mouse is not connected to this
port, the system will reserve IRQ12
for other expansion cards.
Warning:
Make sure to turn off your
computer prior to connecting
or disconnecting a mouse or
keyboard. Failure to do so may
damage the system board.
