Installing the Motherboard
F_USB1~2: Front Panel USB 2.0 headers (F_USB1 supports EZ charger)
The motherboard has two USB 2.0 ports installed on the rear edge I/O port array.
Additionally, some computer cases have USB 2.0 ports at the front of the case. If you
have this kind of case, use auxiliary USB 2.0 connectors to connect the front-
mounted ports to the motherboard.

equipped with instrusion detection switch and needs to be enabled in BIOS.

Unlike F_USB2 in this motherboard, F_USB1 supports EZ charger technology, pro-
vides about 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.

indicated above. A different pin assignment may cause damage or system
hang-up.
