 Trusted Execution Technology (Intel
®
 TXT) must ship with 
authenticated control modules, software binaries used to establish a root of trust.
BIOS launches the BIOS ACM (authenticated control module) to establish a static root 
of trust at power-on. The measured launch environment launches the SINIT ACM to 
establish a dynamic root of trust at MLE (Measured Launch Event) launch.
