(Get the code!)
TPM in this BIOS supports 4 types of PCR: SHA1, SHA256, SHA384, SM3_256.
SHA256 the default.
Next I tried SHA256 & SM3_256
Next I tried all 4 OFF
Finally I tried all 4 ON.
The results each time is the same. When the system boots it displays a message asking if I want to use the new TPM settings (F12 to accept) and then the system starts to boot up, getting the same error message I posted before. The PCR settings don't seem to matter.
