"Power-On / Setup Password
These systems include a power-on and setup passwords, which may be enabled or disabled
(cleared) through a jumper on the system board. The jumper controls a GPIO input to the 82801
ICH9 that is checked during POST. The password is stored in configuration memory (CMOS)
and if enabled and then forgotten by the user will require that either the password be cleared
(preferable solution and described below) or the entire CMOS be cleared (refer to section 4.4.1).
To clear the password, use the following procedure:
1. Turn off the system and disconnect the AC power cord from the outlet and/or system unit.
2. Remove the cover (hood) as described in the appropriate User Guide or Maintainance And
Service Reference Guide. Insure that all system board LEDs are off (not illuminated).
3. Locate the password clear jumper (header is colored green and labeled E49 on these systems)
and move the jumper from pins 1 and 2 and place on (just) pin 2 (for safekeeping).
4. Replace the cover.
5. Re-connect the AC power cord to the AC outlet and/or system unit.
6. Turn on the system. The POST routine will clear and disable the password.
7. To re-enable the password feature, repeat steps 1-6, replacing the jumper on pins 1 and 2 of
header E49."
