Problem Solving 5-15Enable F2 Prompt by Changing a Jumper and Using SSUIf you do not have an SSU diskette or CD available, you can clear CMOS memory to enable the F2prompt. This means you must change a jumper on the system board, run the SSU, save yourchanges, and change the jumper back to the default setting.CAUTIONThis procedure resets all to default settings: Clearing CMOS memory resets allSSU and Setup settings to their defaults, not just the CMOS CLR setting. Beforeproceeding, check that you have a backup paper copy of configuration. Referring tothe worksheets could make your reconfiguration task easier.1. Observe the safety and ESD precautions stated at the beginning of this chapter.2. Turn off all connected peripherals, turn off system power, and disconnect the AC power cord.3. Remove the side cover. Refer to the “Upgrades and Options” chapter for information onremoving the side cover. You do not need to remove the system board from the chassis, andyou probably do not need to remove any add-in boards.4. Locate the CMOS configuration jumper at the edge of the system board toward the front of thesystem. Refer to the “Configuring Your System” chapter for information on the location of theCMOS jumper.5. Move the CMOS CLR jumper from the CMOS Protect setting on pins 1 and 2 to the CMOSClear setting on pins 2 and 3.6. Reinstall the side cover for your safety, and connect the power cord to the system.7. Power on the system. POST starts and halts displaying an “Invalid CMOS Settings” error.8. Turn off the system, and disconnect the power cord.9. Again remove the side cover.10. Move the CMOS CLR jumper from pins 2 and 3 back to pins 1 and 2 (the Protect CMOSmemory position).11. Reinstall the side cover, and connect the power cord.12. Turn the system on. Run BIOS Setup (F2) to verify the correct settings. Refer to Chapter 3 forinformation on running BIOS Setup.Bootable CD-ROM Is Not DetectedCheck the following:n Is the BIOS set to allow the CD-ROM to be the first bootable device? Check your BIOS Setup(F2) configuration.Problems with the NetworkThe server hangs when the drivers are loaded:n Change the PCI BIOS interrupt settings. Try the “PCI Installation Tips” below.Diagnostics pass, but the connection fails:n Make sure the network cable is securely attached.n Make sure you specify the correct frame type in your NET.CFG file.The Link LED doesn’t light:
