Use this jumper to clear the password if the password is forgotten. The default setting is
pins 27-29, (password enabled). To clear the password, turn off the computer, move the jumper to
pins 25-27, and turn on the computer. Then turn off the computer, and return the jumper to pins
27-29 to restore normal operation. If the jumper is in the 25-27 position (password disabled), you
cannot set a password.
