Enable F2 Prompt By Changing A Jumper And Using Ssu - NEC LS2400 User 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: C learing 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 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 CMOS memory 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 for information on running BIOS Setup.
