operation will permanently reset old BIOS settings to factory defaults.
Procedures of CMOS clear:
5.4.1.1 Turn off the system and unplug the power cord from the power outlet.
5.4.1.2 To clear the CMOS settings, use the jumper cap to close pins 2 and 3 for about
3 seconds then reinstall the jumper clip back to pins 1 and 2.
5.4.1.3 Power on the system again.
5.4.1.4 When entering the POST screen, press the <F1> or <DEL> key to enter CMOS
Setup Utility to load optimal defaults.
5.4.1.5 After the above operations, save changes and exit BIOS Setup.

voltage for PCI-104 Plus device.The default for this jumper is “all open”, meaning
the user must select the voltage to be used.
3. BZ:onboard buzzer.
4. JCOM6: (2.0mm Pitch 1x3 Pin Header) COM6 setting jumper, pin 1~3 are used to
select signal out of pin 10 of COM6 port.

Pin1-3: HDD LED, They are used to connect hard disk activity LED. The LED blinks
when the hard disk is reading or writing data.
Pin2-4: POWER LED, They are used to connect power LED. When the system is
powered on or under S0/S1 state, the LED is normally on; when the
system is under S4/S5 state, the LED is off.
Pin5-6: POWER on/off Button, They are used to connect power switch button.
The two pins are disconnected under normal condition. You may short
them temporarily to realize system startup & shutdown or awaken the
system from sleep state.
Pin7-8: RESET Button, They are used to connect reset button. The two pins are
dis-
connected under normal condition. You may short them temporarily to
realize
system reset.
Pin9-10: BUZZER, They are used to connect an external buzzer.
