Figure 11: Clear CMOS Jumper (CLRCMOS1)
The jumper CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to
default values, please turn off the computer and unplug the power cord from the power supply. After waiting for 15
seconds, use a jumper cap to short Pin 2 and Pin 3 on CLRCMOS1 for 5 seconds.
Note:
Do not clear the CMOS immediately after a BIOS update. Reboot the system first, then shut it down before
clearing the CMOS. The password, date, time, user default profile and MAC address will be cleared only if the
CMOS battery is removed.
