Hi, Joe Thank you for various answers. I still have several questions. I would be appreciate if you answer the question. 1)Is SHA256 planned to use? (since definition exists in code) Following questions are from Intel TXT Spec(Aug 2007) 2)What is GV3 MSRs?(p.69) 3)In Intel TXT Specification(August 2007) Appendix D.1.3 - D.1.5 seems old(since same Data Struct is written in Appendix C) 4)In Intel TXT Specification(August 2007) p.59 (see Appendix "0") should be Appendix "C" >From Intel 64 and IA-32 Software Developers Manual. 5) Where is the following manual? Trusted Execution Technology Measured Launched Environment Programming Thanks Atsushi SAKAI |

Appendix D is for the TEP only and so these are legacy data structure versions. > 4)In Intel TXT Specification(August 2007) > p.59 (see Appendix "0") > should be Appendix "C" Good catch--we'll fix it in the next rev. >> From Intel 64 and IA-32 Software Developers Manual. > 5) Where is the following manual? > Trusted Execution Technology Measured Launched Environment Programming That is the title for the next revision of the TXT Preliminary Architecture Specification.
