SMI Transfer Monitor (STM)

This capability is a virtualization agent called the SMI Transfer Monitor (STM) that runs in system management mode (SMM)

The STM is ideally suited to work with a Intel® Trusted Execution Technology (TXT) launch, but the recently released specification includes chapter 12 of STM User Guide V1.0 PDF  for a VT-only usage. This allows for investigation and research around this technology on any system with Intel Virtualization Technology (VT) support, such as with the MinnowBoard Max
