Windows 10: Trying to find a TPM 2.0 Trusted Platform Module 20pin daughter board for ASUS M5A97 EVO...

Oh ! so this is where the Microsoft Newsgroups went to ! Actually, I stumbled on the MS "Communities" once or twice, more recently but, being 67 yr's old, things get more difficult with age !I retired March 2022, so now have time to get this PC working and up to scratch for my 72 yr. old Aunt next door whose old PC M3N78+Athlon dual core, is starting to show its age. Built when my scooter and I were crushed between a high kerb and a petrol tanker, and so was laid up for 6 weeks with a fractured tibia, - this 8 year old Asus M5A97 EVO rev.2.0 / AMD 8320cpu / ddr3 memory / 256gb SSD boo

Bitlocker and Trusted Platform Module problems

We appreciate the screenshot you sent.

This issue usually occurs because the Trusted Platform Module (TPM)
uses the manufacturer driver and not the Windows built-in Trusted Platform Module driver.

To resolve this, you can manually uninstall and reinstall Trusted Platform Module. To do so, see the steps below:

• Open Device Manager on the device on which you are experiencing the issue
• Uninstall the Trusted Platform Module driver.

Give us an update after following the troubleshooting steps provided.

 

Verify Trusted Platform Module (TPM) Chip on Windows PC


Something I came across not long ago, is Firmware-based Trusted Platform Modules (fTPM). Whereas before in order to take advantage of a TPM you needed to have a physical TPM chip soldered to the motherboard, that seems to have changed at some point. You can now have either a Discrete TPM (Physical chip) or Firmware-based TPM.

As per THIS article, fTPM is acknowledged by the Trusted Computing Group (TCG) as a perfectly valid form of TPM and seems to perform much the same functions as a physical TPM. For Intel, their fTPM is called Intel Platform Trust Technology (PTT). I don't know what chips/motherboards/BIOS support PTT, however due to it being Firmware based (as the name suggests) and not requiring a separate physical chip, it means for some devices it's possible to retrospectively add a TPM to devices that didn't have one before.

Looking through the Intel NUC list, it's not just 6th gen Skylake NUC's that it's supported on, but also 5th gen Broadwell NUC's and 4th gen Haswell NUC's too. So if you have a NUC and you have the latest BIOS, then the chances are you have a TPM 2.0 module even if you didn't think you did. You just need to enable 'Intel Platform Trust Technology' in BIOS. As previously mentioned, I don't know what other manufacturers support/will support fTPM too.


The Intel Platform Trust Technology (PTT) setting in Intel VisualBIOS:





With Intel PTT on in BIOS, Device Manager and tpm.msc show a TPM 2.0 module installed.

 

Initialisation of the Trusted Platform Module (TPM) failed

I'm not finding any specific issues on Win 10 1909, but ironically, there are a couple of known TPM issues on 2004.

If you do upgrade to 2004, I would suggest installing the currently available Cumulative Update Preview KB457144.

From the list of fixes there are 2 TPM related issues addressed:

1) Addresses an issue that causes communication with the TPM to time out and fail.

2) Addresses an issue that prevents hash signing from working correctly when using the Microsoft Platform Crypto Provider for Trusted Platform Modules (TPM). This issue might also affect networking software, such as virtual private network (VPN) applications.
