Asus P5KC - Manual (Page 59)

ASUS P5KC 2-35
8. Optical drive audio connector (4-pin CD [Black])
These connectors allow you to receive stereo audio input from sound sources
such as a CD-ROM, TV tuner, or MPEG card.
7. IEEE 1394a port connector (10-1 pin IE1394_2)
This connector is for a IEEE 1394a port. Connect the IEEE 1394a module
cable to this connector, then install the module to a slot opening at the back
of the system chassis.
Never connect a USB cable to the IEEE 1394a connector. Doing so will damage
the motherboard!
You can connect the 1394 cable to ASUS Q-Connector (1394, red) first, and
then install the Q-Connector (1394) to the 1394 connector onboard.
The IEEE 1394 module is purchased separately.
