Remove the system cover.
Move the jumper on the system board from pins 2 and 4 to pins 4 and 6.

NOTE:The existing passwords are not disabled (erased) until the system boots with the jumper on pins 4 and 6. However, before you assign a new system and/or setup password, you must move the jumper back to pins 2 and 4.
NOTE:If you assign a new system and/or setup password with the jumper on pins 4 and 6, the system disables the new password(s) the next time it boots.
