These headers can support an IEEE-1394 serial connector cable set that mounts
to the front of a case with a 1394 connector slot for easy accessibility or an
IEEE-1394/COM2 combination serial connector cable set that mounts to a free
expansion slot at the back of your case. You can also connect 1394-compliant
internal fixed-disk drives to these headers. NOTE: To use these headers, set

15) Internal Audio Connectors (4-pin MODEM, CD_IN, AUX_CON, VIDEO)
These connectors allow you to receive stereo audio input from sound sources,
such 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 connec-
tor. It also allows the sharing of microphone and speaker between the onboard
audio and the voice modem card.
