IMB-8550
In case the motherboard fails to boot due to user’s improper BIOS setting, this jumper can
be used to clear the CMOS data and reset the system BIOS information. To clear the
CMOS contents, shunt pins 2 and 3 for a few seconds, and then reinstall the jumper clip
back to pins 1 and 2.
If the “CMOS Settings Wrong” message displays during the boot up process, you may
then try to correct the fault by pressing the F1 to enter the CMOS Setup menu. You may
then enter the correct CMOS setting, Load Optimal Defaults, or Load Failsafe Defaults.
Save your changes and exit the CMOS Setup menu.
