TPM_E_PPI_BIOS_FAILURE

TPM_E_PPI_BIOS_FAILURE means firmware prevented the requested TPM physical-presence operation from completing. The failure can result from an invalid PPI request, BIOS-to-TPM communication, or firmware policy.

What to check

Record the requested physical-presence action and inspect the firmware TPM/security settings.
Check OEM release notes for BIOS or TPM firmware updates that address TPM management issues.
Do not treat this as a Windows-only permission problem; the failure occurred in the platform firmware path.
