Uses of the Management Engine

The management engine(Often abreviated ME) is a CPU which permits Out of band management of the computer.

Freedom and security issues

  • The code that is running inside the management engine is proprietary and signed
  • The management engine CPU has access to a lot of things, see "ME physical capabilities" for more details.
