After you finish the setting of jumpers and connect correct cables. Power on and enter the BIOS Setup, press <Del> during POST (Power On Self Test). Choose "Load Default Setting" for recommended optimal performance.
16. Wake On LAN
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 a 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.
17. Installing Onboard Sound Driver
This motherboard comes with an AD 1885 AC97 CODEC, you can find the audio driver from the Bonus Pack CD disc
If you encounter any trouble to boot you system, follow the procedures accordingly to resolve the problem.
Turn off the power and unplug the AC power cable, then remove all
of the addon cards and cables, including VGA, IDE, FDD, COM1,
COM2 and Printer.
Make sure if the jumper settings for CPU and DRAMs are correct.
Install the VGA card. Then connect your monitor and keyboard.
Turn on the power, and check if

The problem was probably caused by power supply or motherboard failure. Please contact your reseller or local distributor for repairing.
Perhaps your VGA card or monitor is defective.
It is very possible that your keyboard is defective.
The problem should be caused by the IDE cables or HDD itself.
