Password Clear

If the User or Administrator password(s) is lost or forgotten, both passwords may be cleared by
moving the password clear jumper into the "clear" position. The BIOS determines if the
password clear jumper is in the "clear" position during BIOS POST and clears any passwords if
set. The password clear jumper must be restored to its original position before a new
password(s) can be set.
