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 45. 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
that came with your system.
1 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2 Open the system. See "Opening and Closing the System" on page 66.
3 Lift up the memory module shroud.
4 Remove the jumper plug from the password jumper.
See Figure 6-1 to locate the password jumper (labeled "PWRD_EN") on
the system board.
5 Close the system.
6 Reconnect your system and peripherals to their electrical outlets, and turn
on the system.
The existing passwords are not disabled (erased) until the system boots
with the password jumper plug removed. However, before you assign a new
system and/or setup password, you must install the jumper plug.
NOTE: If you assign a new system and/or setup password with the jumper
plug still removed, the system disables the new password(s) the next time it
boots.

the system from the electrical outlet.
