My motherboard P8H67-M-EVO has a slot for TPM module - 20-1 PIN, however, it does not seem to recognise the module TPM-L R2.0.

In BIOS // Advances // Trusted Computing, I can enable "TPM Support" and "TPM Device", but after reboot, the "TPM Device" is disabled again (while "TPM Support" stays enabled).

The MB documentation does not say which version of TPM is support. My understanding is that external modules are always TPM 2.0.

Any idea how to get TPM-L R2.0 working?
