You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin 1 & pin2.
5. Connect ATX power cable back to connector PWR2.

With this motherboard, AOpen provides a very special, useful feature for overclockers. When you
power-on the system, the BIOS will check last system POST
enable “Watch Dog Timer” function immediately, and set the CPU FSB
that stored in the BIOS. If system failed in BIOS POST, the “Watch Dog Timer” will reset the
system to reboot in five seconds. Then, BIOS will detect the CPU’s default frequency and POST
gain. With this special feature, you can easily overclock your system to get higher system performance, and without removing
a
he cover of system housing to set the jumper to clear CMOS data when your system hanged.

IDE1 is also known as the primary channel and IDE2 as the secondary channel. Each channel supports two IDE devices that
make a total of four devices. In order to work together, the two devices on each channel must be set differently to Master and
Slave mode. Either one can be the hard disk or the CDROM. The setting as master or slave mode depends on the jumper on
your IDE device, so please ref er to your hard dis k and CDROM manual acc ordingly.
This motherboard supports ATA33
modes. The IDE bus is 16-bit , which means every transfer is two bytes.

This feature is very similar as Wake On Modem, but it goes through local area network. To use Wake On LAN function, you must
have a network card with chipset that supports this feature, and connect a cable from LAN card to motherboard WOL connector.
The system identification information (probably IP address) is stored on network card and because there is a lot of traffic on the
Ethernet, you need to install network management software, such as ADM, for the checking of how to wake up the system. Note
that, at least 600mA ATX standby current is required to support the LAN card for this function.

the operating system. It can even clearly “tell” whether there is a component issue or an installed issue, such as CPU, memory

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,
new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This
motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power
supply for providing full line over-c urrent prot ect ion.
Note: Although we have implemented protection circuit try to prevent any human operating
mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this
motherboard may be damaged because of component failure, human operating error or unknown
nature reason. AOpen cannot guaranty the protection circuit will always work perfectly.

The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the
stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail
