26 Maintaining and Troubleshooting the Gateway ALR 7200 ServerClear CMOS JumperThe Clear CMOS jumper (JP15) lets you clear all current values incomplimentary metal-oxide semiconductor (CMOS) memory. CMOSmemory stores all of the BIOS Setup information and settings. Clearing theCMOS memory restores all setup values to the original system defaults.A jumper shunt connecting pins 1 and 2 is for normal operations. A jumpershunt connecting pins 2 and 3 is for clearing the CMOS memory.1. You must restart the server and press F2 to enter the BIOS Setup utility.2. Write down the current BIOS configuration settings for laterreference.3. Turn off the system and disconnect the power cord.4. Open the case, observing the static electricity precautions inChapter 1.5. Move the jumper shunt on the Clear CMOS (JP15) jumper to connectpins 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 itsnormal position connecting pins 1 and 2.9. Close the case, as described in Chapter 1.10. Reconnect the power cord and turn on the system.Clearing the CMOS memory clears all passwords and all configurationsettings. You will need to reset any necessary values in BIOS Setup afteryou clear CMOS memory.To clear CMOS memory
