Clear CMOS jumper

JP15 lets you clear all current values in complimentary metal-oxide semiconductor (CMOS) memory. CMOS memory stores all of the BIOS Setup information and settings. Clearing the CMOS memory restores all setup values to the original system defaults.

A jumper shunt connecting pins 1 and 2 supports normal operations. A jumper shunt connecting pins 2 and 3 clears the CMOS memory.

To Clear CMOS Memory

1.Turn off the system and disconnect the power cord.

2.Open the case, observing the ESD precautions in “Static electricity precautions” on page 2.

3.Move the jumper shunt on the JP15 jumper to connect pins 2 and 3.

4.Wait a few seconds (5–10) while the CMOS memory clears. It is not necessary to start up the system to clear CMOS memory.

5.Move the jumper shunt on the JP15 jumper back to its normal position connecting pins 1 and 2.

6.Close the case, as described in “Closing the system” on page 7.

7.Reconnect the power cord and turn on the system.

Clearing the CMOS memory clears all passwords and all configuration settings. You must reset any necessary values in BIOS Setup after you clear the CMOS memory.

Important!

If the error message “update table not found for CPUxx, Stepping xxxx” displays at boot up, run the MULOADER utility located on the disk included with your processor kit. This message may occur under the following conditions: When a new processor has been added that does not include the stepping information in the table. When the BIOS is flashed, it may remove the stepping information form the table which will cause the error message to appear.
