comment TPM PCR value unchanged with BIOS configuration changes
You should probably close the question by answering to yourself with the latest update: seems like even though a computer has a TPM, doesn't mean it actually works... or something similar.

Could you elaborate on how you retrieve the measurements? e.g. in linux "cat /sys/devices/pnp0/00:09/pcrs"
