There are 3 modes or stages that the AMT system has to go through before it is operationa- factory mode, setup mode and operational mode. AMT system comes from factory in factory mode whereAMT is unconfigured. When the user configures the AMT settings through Bios, it enters into setup mode. This is the stage where it waits for configuration settings from SCS. Please read more about this processes in the Developers' guide for SCS
