+ help
+ The Secure Launch feature allows a kernel to be loaded
+ directly through an Intel TXT measured launch. Intel TXT
+ establishes a Dynamic Root of Trust for Measurement (DRTM)
+ where the CPU measures the kernel image. This feature then
+ continues the measurement chain over kernel configuration
+ information and init images.
