You may need to clear the CMOS if your system cannot boot up because
you forgot your password, the CPU clock setup is incorrect, or the CMOS
settings need to be reset to default values after the system BIOS has been
updated. Refer to the following solutions to reset your CMOS setting:
Solution A:
1. Power off the system and disconnect the power cable.
2. Place a shunt to short pin 2 and pin 3 of JBAT1 for five seconds.
3. Place the shunt back to pin 1 and pin 2 of JBAT1.
4. Power on the system.
Solution B:
If the CPU Clock setup is incorrect, you may not be able to boot up. In this
case, follow these instructions:
1. Turn the system off, then on again. The CPU will automatically boot up
using standard parameters.
2. As the system boots, enter BIOS and set up the CPU clock.
Note:
If you are unable to enter BIOS setup, turn the system on and off a
few times.
