Un-provision
The Un-Provision option allows you to reset the Intel AMT configuration to factory defaults. There are two types of un-
provision:
Full Un-provision – This option resets all of the Intel AMT settings to their default values. If a PID/PPS value is
present, both values are lost. The MEBx password remains untouched.
CMOS clear – This un-provision option is not available in the MEBx. This option clears all values to their default values.
If a PID/PPS is present, both values are lost. The MEBx password resets to the default value (admin). To invoke this
option, you need to clear the CMOS (i.e. system board jumper).
