Internal Audio Connectors

6. Internal audio connectors (4-pin CD_IN, AUX_CON)

(optional)

These connectors allow you to receive stereo audio input from sound
sources such as a CD-ROM, TV tuner, or MPEG card.

7. IEEE-1394 headers (two 8-pin 1394HEAD2, 1394HEAD3)

(optional)

These headers connect the 1394 serial connector cables (8-to-6 pin
cables) from the 2-port 1394 module. Connect the 8-pin connectors to
these 8-pin headers, and the 6-pin connectors to the 1394 module.

You may also connect 1394-compliant internal hard disk drives to
these headers.
