I've begun experimenting with BitLocker. I'm trying to enable it on a Tecra M5, which is several years old. I suspect the TPM on this unit may be a version that is too old to support BitLocker, but how can I tell for sure what version this unit has? When I enabled BitLocker, the system restarted, asked me to initialize the TPM, and all appeared to be well. However now, whenever I restart and try doing the check before actually encrypting the drive, I get an error indicating that my boot configuration has changed and the check fails. Has anyone else experienced this, and does it indicate the presence of a TPM 1.0 or 1.1 as opposed to a 1.2? I would think if the TPm were too old, BitLocker would be smart enough to just say so and not proceed any further?
