This 3-pin jumper block determines the BIOS Setup utility mode. When the jumper is set to configuration mode and the computer is started, the BIOS compares the processor version and the microcode version stored in the BIOS. It then reports if the two match.

Note: Do not move any jumper with the power on. Always turn off the power before changing a jumper setting. Damage to the motherboard may occur if power is left on while moving the jumper.

To clear BIOS passwords, enter the Maintenace Menu by placing the jumper on pins two and three. Place back on pins one and two when completed.
