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 2-6.
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 SCU to verify the correct settings. See Chapter 3.
Password Jumper
The jumper at pins 5, 6, and 7 controls whether a stored password is retained
or cleared during a system reset.
Procedure to clear the current password and then enter a new one:
1.
See “General Procedure to Change Jumper Setting” on page 2-6.
2.
Move the Password jumper from pins 5 and 6 to pins 6 and 7.
3.
Reinstall the side cover for your safety, and connect the power cord to
the system.
4.
Turn the system on, and wait for POST to complete. This automatically
clears the password.
5.
Turn off the system, and disconnect the power cord.
6.
Again remove the side cover.
7.
Move the jumper from pins 6 and 7 back to pins 5 and 6.
8.
Reinstall the side cover, and connect the power cord to the system.
9.
Run the SCU to specify a new password. See Chapter 3.
Recovery Boot Jumper
The jumper at pins 9, 10, and 11 controls whether the system attempts to boot
using the BIOS programmed in Flash memory.
Procedure to disable recovery booting:
1.
See “General Procedure to Change Jumper Setting” on page 2-6.
2.
Move the recovery boot jumper from pins 9 and 10 to pins 10 and 11.
