To clear and reset the system parameters to default setup, 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 pin2 and pin3 on CLRTC1 for 5 seconds. However, please do not clear the CMOS right after you update the BIOS.
