Keylock Security

      Disclosed is a method to supplement keylock security with a
password stored in NVRAM.  This method requires no new hardware.

      Currently, keylocks provide security using a mechanical switch
that is rotated to cause a register to be read, either locking or
unlocking a system.  Using a password to secure the system adds a
level of security while eliminating the need to use the key to lock
or unlock the system.

      In this invention, a password is stored in the NVRAM of the
Real-Time Clock (RTC).  The security sequence is described below:
  o  First, the system checks NVRAM to see if a password is present
      (Figure).
  o  If a password is present, the keylock is checked.  If no
password
      is present, the system is booted.
  o  If the keylock is in the "lock" position, the user is prompted
to
      enter the password.  If the keylock is not locked, the system
is
      booted.
