13. Internal audio connectors (4-pin CD1, AUX1, MODEM1)
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 connector. It also allows the sharing of mono_in
(such as a phone) and a mono_out (such as a speaker) between the
audio and a voice modem card.
14. IEEE 1394 connector (10-1 pin IEEE1394_1)
This connector is for a 1394 module. Attach the 10-1 pin 1394 cable
plug from the module to this connector. You may also connect a 1394-
compliant internal hard disk to this connector.
NEVER connect a USB cable to the IEEE 1394 connector. Doing so
will damage the motherboard!
