Enable F2 Prompt By Changing A Jumper And Using Ssu; Bootable Cd-Rom Is Not Detected - NEC NEAX Express Service & Reference Manual

Enable F2 Prompt by Changing a Jumper and Using SSU

If you do not have an SSU diskette or CD available, you can clear CMOS memory to
enable the F2 prompt. This means you must change a jumper on the system board, run
the SSU, save your changes, and change the jumper back to the default setting.
This procedure resets all to default settings: Clearing CMOS
memory resets all SSU and Setup settings to their defaults, not just
the CMOS CLR setting. Before proceeding, check that you have a
backup paper copy of configuration. Referring to the 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 on removing the side cover. You do not need to remove the system
board from the chassis, and you 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 the system. Refer to the "Configuring Your System" chapter for
information on the location of the CMOS jumper.
5. Move the CMOS CLR jumper from the CMOS Protect setting on pins 1 and 2 to the
CMOS Clear 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 cords.
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
CMOS memory position).
11. Reinstall the side cover, and connect the power cords.
12. Turn the system on. Run BIOS Setup (F2) to verify the correct settings. Refer to
Chapter 3 for information on running BIOS Setup.

Is the BIOS set to allow the CD-ROM to be the first bootable device? Check your
BIOS Setup (F2) configuration.
