14) Internal Audio Connectors (4-pin MODEM, CD_IN, CDROM_AUDIO)
These connectors allow you to receive stereo audio input from such sound sources
as a CD-ROM, TV tuner, or MPEG card. The MODEM connector allows the
onboard audio to interface with a voice modem card with a similar connector. It
also allows the sharing of microphone and speaker between the onboard audio
and the voice modem card.

13) 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.
