      If your Abit Motherboard system hangs while updating the BIOS or when you set the wrong CPU parameters, you should always clear the CMOS jumper before booting up again. This will reset the BIOS to its default settings.

      If your Abit Motherboard fails to boot after overclocking or using non-standard BIOS settings, try the following: 1. Turn off the power supply (or disconnect the power cord), wait one minute, and then turn it back on. While booting, press and hold the key, then press the power button. If successful, release and press to enter BIOS setup and correct the settings. 2. If the first step doesn't work, power down and open the computer case. Find the CCMOS jumper near the battery. Change the jumper from position 1-2 to 2-3 for one minute to clear the CMOS data, then return it to 1-2. 3. As a last resort, repeat step 2, but also remove the ATX power connectors from the motherboard and take out the button battery while discharging the CMOS.
