Installing the Motherboard
F_AUDIO: Front Panel Audio header
This header allows the user to install auxiliary front-oriented microphone and line-
out ports for easier access.
F_USB1~3: Front Panel USB 2.0 headers
The motherboard has six USB ports installed on the rear edge I/O port array. Addi-
tionally, some computer cases have USB ports at the front of the case. If you have
this kind of case, use auxiliary USB connector to connect the front-mounted ports to
the motherboard.
Please make sure that the USB cable has the same pin assignment as
indicated above. A different pin assignment may cause damage or system
hang-up.

Unlike F_USB2~3 in this mainboard, F_USB1 supports EZ Charger technology
(optional), provides 1A current than general USB port in off mode for USB devices.
It is useful and excellent, especially for the iPhone, iPad and iPod touch devices that
need a large amount of current for faster recharging within less time.
