(not supplied) will accomplish the following:
• Return all Intel ME parameters to their default values.
• Delete any user entered information, including PID/PPS and user entered Hash
Certificates. USB key and remote configuration data will be removed if the
parameters are not default parameters.
• Reset the Intel MEBX password to the default value (admin).
