Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are discussed
in detail in "Using the System Setup Program" on page 37. The password jumper enables these password
features or disables them and clears any password(s) currently in use.
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your Product Information
Guide.

plug.

disables the new password(s) the next time it boots.
