Password Clear 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 152.
2. Move the Password jumper from pins 5 and 6 to pins 6 and 7.
3. Reinstall the access cover for your safety (using the original screws), and connect the power
cords 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 all AC power cords.
6. Again remove the access cover.

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 152.
2. Move the recovery boot jumper from pins 9 and 10 to pins 10 and 11.
3. Reinstall the access cover for your safety (using the original screws), then connect the power
cords to the system.
4. Turn the system on, and insert the Flash Memory Update Utility diskette in drive A. After the
system boots, the speaker emits a single beep and the recovery process starts. This takes about
three minutes. When the recovery process completes, the speaker emits two beeps.
While in the recovery mode, there is no screen display on the monitor. The keyboard is disabled as
the system automatically recovers the BIOS. The following beep codes describe the recovery
status.
