between Front USB connector and USB modules or chassis front

With IEEE1394 Chip on board (AGERE 1394), having its data transfer rate up
to 400Mb/s, this interface can connect to devices that require high data
transferring performance such as digital camera, scanner or others IEEE 1394
devices. Please use appropriate cables to connect IEEE1394 devices.

Setting CPU Voltage & Frequency

Setting CPU Core Voltage

This motherboard supports Voltage ID (VID) function to detect CPU voltage automatically

during power-on.

Setting CPU Frequency

This motherboard is CPU jumper-less design, set CPU frequency through 1MHz stepping CPU

Overclocking in the BIOS. CPU Core Frequency = CPU external frequency x CPU Ratio.

However, all CPU now selling in the market belong to "Fixed Multiplier". That means users can

not adjust the CPU Ratio but only change CPU FSB clock to achieve over-clocking.

(Users do the over- clocking at their own risk!)

You can clear CMOS to restore system default setting. Follow the procedure below.

Turn off the system and unplug the AC power.

Remove ATX power cable from connector PWR3.

Locate JP14 and short pins 2-3 for a few seconds.

Return JP14 to its normal setting by shorting pin 1 & pin 2.

Connect ATX power cable back to connector PWR3.

Front Audio Connectors

If the housing has been designed with an audio port on the front panel, you’ll be able to

connect onboard audio to front panel through this connector. By the way, please remove 5-6

and 9-10 jumper caps from the Front Audio Connector before connecting the cable. Please do

not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on the front panel.

Over-clocking not guarantee by AOpen. AOpen MB design is
under intel & industry standard. Over-clocking may cause your
system unstable and damage. Please be careful on using it.

Tip: When you fail to over-clock, you could:

Clear CMOS (JP14) to restore the default setting.
After turning power on, press “Home” immediately until the screen

appears.

This motherboard provides keyboard / mouse wake-up function. You can use JP28 to enable or

disable this function, which could resume your system from suspend mode with keyboard or

mouse. The factory default setting is “Disable” (1-2), and you may enable this function by setting

the jumper to 2-3.
