... also there are Intel's methods and software to check status and/or
disable it:

the thing is, do you trust intel? do you trust all people who works in
intel? were there big software faults and hidden specification in the
past that let security holes in your machine?

If yes, then the bios changes, the intel's software resoults, and also
the actions taken by iME when faulty firmware is loaded will all be good
and known

If no, we have to go deeper into other ways to disable it, more far than
Intel's given instructions and specifications
