19. IrDA-Compliant infrared module connector (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.

20. ATX Power Supply Connector (20-pin block)
This connector connects to an ATX power supply. The plug from the power
supply will only insert in one orientation because of the different hole sizes.
Find the proper orientation and push down firmly making sure that the pins are
aligned.
IMPORTANT: Make sure that the ATX power supply can take at least
10mAmp load on the 5Volt standby lead (5VSB). You may experience diffi-
culty in powering on your system without this.
