Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are

. The password
jumper enables these password features or disables them and clears any password(s) currently
in use.
CAUTION: See your System Information Guide for complete information about safety precautions,
working inside the computer, and protecting against electrostatic discharge.
