You should get a copy of the published PC Client TPM spec. It will answer this question and probably a lot more. For security reasons, the only way to reset PCR 0-15 is to reboot. If you want to know the rationale, read part 1 of the TPM main spec, which discusses the TPM architecture. ------------------------------------------------------------------------------ _______________________________________________ TrouSerS-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/trousers-users
