Power-On Password
A power-on password denies access to the system by an unauthorized user
when the system is powered on. When a power-on password is active, the
password prompt appears on the screen each time the system is powered
on. The system unit boots up after the proper password is entered.
To service a system with an active and unknown power-on password, power
off the system unit and do the following:
For a 386SX system board:
1. Locate connector J8 on the system board.
2. Move the jumper on J8 so that it connects the center pin and the
pin on the opposite end of the connector.
3. Power on the system unit.
The system detects the change and the password is erased from
memory. Leave the jumper in that position until the next time you need
to reset the password.
For 486SX Level 1 and 486DX (30-pin memory SIMM) system boards:
1. Power off the system unit.
2. Locate connector JP8 on the system board.
3. Move the jumper on JP8 so that it connects pins 2 and 3.
4. Apply a momentary short across the two ends of capacitor C17.
C17 is located near the power connector P1.
5. Move the jumper on JP8 back to pins 1 and 2.
6. The system detects the change and the password is erased from
memory.
7. When you are finished servicing the machine, run the Configuration
Utility to restore the configuration settings.
For 486SX Level 2 (30-pin memory SIMM) system boards:
1. Power off the system unit.
2. Locate connector JP8 on the system board.
3. Move the jumper on JP8 so that it connects pins 2 and 3.
4. Locate connector JP59 on the system board.
5. Move the jumper on JP59 so that it connects pins 2 and 3.
