11. IrDA-Compliant Infrared Module Connector (5-pin IR)
This connector supports the optional wireless transmitting and receiving infrared
module. This module mounts to a small opening on system cases that support this
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.

12. ATX Power Supply Connector (20-pin ATXPWR)
This connector connects to a ATX power supply. The plug from the power sup-
ply will only insert in one orientation because of the different hole sizes. Find
the proper orientation and push down firmly but gently making sure that the pins
are aligned.

IMPORTANT: Make sure that your ATX power supply can supply at least
10mAmp on the 5-volt standby lead (5VSB). You may experience difficulty in
powering on your system if your power supply cannot support the load. For
Wake on LAN support, your ATX power supply must supply at least 720mA.
