9) IrDA-Compliant Infrared Module Connector (5-pin IR)
This connector supports the optional wireless transmitting and receiving infra-
red module. This module mounts to a small opening on system cases that sup-
port this feature. You must also configure the setting through UART2 Use In-
frared (see 4.4.2 I/O Device Configuration) to select whether UART2 is di-
rected for use with COM2 or IrDA. Use the five pins as shown in Back View and
connect a ribbon cable from the module to the motherboard according to the pin
definitions.

10) USB, Infrared, PS/2 Mouse Module Connector (18-1 pin USBIRMS)
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 one is not detected, expansion cards can use IRQ12. See PS/2 Mouse
Function Control in 4.4 Advanced Menu and USB Function in 4.4.3 PCI Con-
figuration. See IrDA-Compliant Infrared Module Connector above for
details on the infrared connector.
