Chapter 1: Introduction
A. How the TXT Works
The Intel TXT, when enabled, follows a step-by-step process to ensure security of
pre-launch components.
1. Measures the hypervisor launch upon system startup
2. Checks for a match
3. If matched: The TXT signals "trusted," and the launch is allowed to proceed.
4. If mismatched: The TXT signals "untrusted," and the launch is blocked.
1.4 Motherboards Supported
Please refer to the Supermicro website (http://www.supermicro.com/) for a com-
plete and most up-to-date list of the motherboards that can support the TPM. As a
general rule, these are most X9 motherboards, all X10 motherboards, and some
AMD motherboards. Such motherboards will have a specially designated JTPM1
connector, which will be listed in the respective motherboard's manual.
