16. USB, PS/2 Mouse, IrDA Module Connector (18-1 pin USB/MIR)

If you want to use USB or infrared (IrDA) devices, you need to purchase an exter-
nal connector set. The external connector set, which also includes a PS/2 mouse
connector, connects to the 18-pin block and mounts to an open slot on your
computer’s chassis. The system will direct IRQ12 to the PS/2 mouse if one is
detected. If not detected, expansion cards can use IRQ12. See “PS/2 Mouse Con-
trol” in BIOS Features Setup and “USB Function” in PnP and PCI Setup of BIOS
SETUP. See IrDA-Compliant... connector for details on the infrared connector.

This connector supports the optional wireless transmitting and receiving infrared

feature. You must also configure the setting through “UART2 Use Infrared” in
Chipset Features Setup to select whether UART2 is directed for use with COM2
or IrDA. Use the five pins as shown on the Back View and connect a ribbon cable
from the module to the motherboard according to the pin definitions.
