34 Maintaining and Troubleshooting the Gateway ALR 7200 Server
Clear CMOS jumper
The 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 is for normal operations. A jumper
shunt connecting pins 2 and 3 is for clearing the CMOS memory.
1. You must restart the server and press F 2 to enter the BIOS Setup utility.
2. Write down the current BIOS configuration settings for later
reference.
3. Turn off the system and disconnect the power cord.
4. Open the case (“Opening the system” on page 3), observing the static
electricity precautions in “Static electricity precautions” on page 2.
5. Move the jumper shunt on the Clear CMOS (JP15) jumper to connect
pins 2 and 3.
6. Reconnect the power cord and turn on the system.
7. Turn off the system again and disconnect the power cord.
8. Move the jumper shunt on the Clear CMOS (JP15) jumper back to its
normal position connecting pins 1 and 2.
9. Close the case, as described in “Closing the system” on page 8.
10. Reconnect the power cord and turn on the system.
Clearing the CMOS memory clears all passwords and all configuration
settings. You will need to reset any necessary values in BIOS Setup after
you clear CMOS memory.
