A990FXM-A USER MANUAL
The motherboard has two USB 2.0 headers supporting four USB 2.0 ports. Addition-
ally, 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.
Unlike F_USB2 in this mainboard, F_USB1 supports EZ Charger technology (optional),
provides 3 times 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.
2. F_USB1~2: Front Panel USB 2.0 headers
Please make sure that the USB cable has the same pin assignment as indi-
cated above. A different pin assignment may cause damage or system hang-
up.
3. CASE: Chassis Intrusion Detect Header
This detects if the chassis cover has been removed. This function needs a chassis
equipped with instrusion detection switch and needs to be enabled in BIOS.
