User(Power-On) Password

A user password denies access to the system by an
unauthorized user when the system is powered on.
When a user password is active, the password
prompt appears on the screen each time the system
is powered on. The system starts after the proper
password is entered. See "User(Power-On)
Password" on page 9 for more information about how
to change, remove and set password in
Configuration/Setup Utility.
In some cases, you might be required to service a
system with an active and unknown user password.
To clear a password from the system, follow these
steps.
1. Turn off system unit.
2. Unplug power cable from the electrical outlet.
IMPORTANT: Do not attempt these steps with the
power cord plugged into the electrical outlet.
The power supply maintains +5 Vdc of standby
power when the power cord is plugged.
System damage might result if the power cord
is not unplugged during jumper setting.
3. Set JP33 to 2-3 position to clear BIOS setting as
original manufacture setting. See "System Board
Jumpers and Connectors" on page 117.
IMPORTANT: To reinstall the password, the user
must enter a password in the Configuration/Setup
Utility. If Enhanced Security is enabled and the
password is forgotten, the system board must be
replaced.
