Cmos Jumper; Password Jumper - Intel L440GX+ Product Manual

CMOS Jumper

The jumper at pins 1, 2, and 3 controls whether settings stored in CMOS nonvolatile memory
(NVRAM) are retained during a system reset.
Procedure to restore the system's CMOS and RTC to default values:
1. See "General Procedure to Change Jumper Setting" on page 100.
2. Move the CMOS jumper from pins 1 and 2 to pins 2 and 3 (the Clear CMOS memory position).
3. Reinstall the side cover for your safety, and connect the power cord to the system.
4. Turn the system on. Wait for POST to complete and for the messages "NVRAM cleared by
jumper" and "Press F2 to enter Setup" to appear. This automatically reprograms CMOS and
RTC to their default settings.
5. Enter Setup and make any changes necessary (for example, changing the boot device). Press
F10 to save the new Setup configuration and exit Setup.
6. Turn off the system, and disconnect the power cord from the system.
7. Again remove the side cover.
8. Move the jumper from pins 2 and 3 back to pins 1 and 2 (the Protect CMOS memory position).
9. Reinstall the side cover, and connect the power cord to the system.
10. Run BIOS Setup or the SSU to verify the correct settings. See Chapter 3.
