P4V8X-MX USB 2.0 Connectors
5. USB connectors (10-1 pin USB56, USB78)
These connectors are for USB 2.0 ports. Connect the USB module cable to
any of these connectors, then install the module to a slot opening at the back
of the system chassis.
The USB module is purchased separately.
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
6. Internal audio connectors (4-pin CD, AUX)
These connectors allow you to receive stereo audio input from sound sources
such as a CD-ROM, TV tuner, or MPEG card.
