Front Audio Connector: F_AUDIO
The audio interface provides two kinds of audio
output choices: the Front Audio, the Rear Audio.
Their priority is sequenced from high to low
(Front Audio to Rear Audio). If headphones are
plugged into the front panel of the chassis
(using the Front Audio), then the Line-out (Rear
Audio) on the rear panel will not work. If you do
not want to use the Front Audio, pin 5 and 6,
pin9 and 10 must be SHORT, and then the sig-
nal will be sent to the rear audio port.
USB Connectors: F_USB1, F_USB2
Besides four USB ports on the rear panel, the series of motherboards also
have two 10-pin connectors on board which may connect to front panel USB
cable(optional) to provide additional four USB ports.
