Chapter 1 Introduction
1.1 Overview of the Trusted Platform Module (TPM)
The Trusted Platform Module (TPM9670) is a special add-on module that may be
installed onto Supermicro X11 dual and single processor motherboards that
support CPU Socket 3674 only.
Types of TPMs
Note: TPM module must be provisioned in order to support Intel® Trusted
Execution Technology (TXT). Please contact Supermicro Technical Support to get
more details about the Intel tool.
The TPM-9670 series add-on modules use TCG (Trusted Computing Group) version
2.0 firmware.
The following SKUs are available:
- AOM-TPM-9670V, a vertical TPM module
- AOM-TPM-9670H, a horizontal TPM module
Horizontal vs. Vertical: Generally, whether you should use a TPM with a
horizontal or vertical form factor depends on the physical space available.
Horizontal TPMs are used in 1U chassis. Vertical TPMs are used in 2U or taller
chassis, which are designed with a smaller footprint to occupy less space on
the motherboard.
Server vs. Client: To use the TXT function, each TPM has been provisioned as a
server model or client model. Be sure to use the appropriate TPM for your
needs.
Both server TPM and client TPM are designed to support motherboards with
Socket P (LGA3647) processors installed.

1.3 Motherboards Supported for TPM
Please refer to the Supermicro website (http://www.supermicro.com/) for a
complete and most up-to-date list of the motherboards that can support the
TPM. As a general rule, besides the X11 motherboards, the list includes most
X9 motherboards, all X10 motherboards, and some AMD motherboards. These
motherboards will come with a specially designated JTPM1 connector on every
board, which will be listed in the respective motherboard’s manual.
1.4 Intel® TXT
The Intel Trusted Execution Technology (TXT) is a software tool that may be
used in conjunction with the TPM to provide additional security for pre-launch
firmware of clusters and clouds, including but not limited to the BIOS, IPMI,
SAS firmware, and CMM firmware. It is optional, but the TPM is required for it
to be provisioned.
It will further enhance system security by protecting firmware against
malicious attacks on vulnerable areas.
It works by matching hypervisor measures with encryption keys upon system
launch.
If the hypervisor does not match the keys, the hypervisor will be prevented
from starting up.
To use the TXT, you need to enable TXT support after provisioning the TPM.
Note: TXT is only supported on Intel platforms that support TPM use.
How the TXT Works
The Intel TXT, when enabled, follows a step-by-step process to ensure the
security of pre-launch components.
- Measures the hypervisor launch upon system startup
- Checks for a match
- If matched: The TXT signals “trusted,” and the launch is allowed to proceed.
- If mismatched: The TXT signals “untrusted,” and the launch is blocked.
Chapter 2 Deploying and Using the TPM
Follow the instructions below to begin using the TPM.
2.1 Installing the TPM Onto the Motherboard
To install the Trusted Platform Module onto your motherboard, follow the steps
below.
- Find the 9-pin male JTPM1 connector on the motherboard. If you need help locating this connector, consult your motherboard manual. If the board does not have this feature, then it does not support the TPM.
- Using the key pin as a reference, orient, and align your TPM with the connector.
- Carefully insert the TPM into the connector on the motherboard, making sure not to damage the pins.
Note: The orientation of the TPM to be installed depends on whether it has a horizontal or vertical form factor. The vertical TPM is intended to “stand” perpendicular to the motherboard, while the horizontal TPM lies flat (parallel) on the motherboard. See the below two images for the correct orientation.
2.2 Enabling the TPM via the BIOS and Intel® Provision Utility
There are two components to the process of enabling the TPM. After you have
installed the TPM onto the motherboard, you must first “verify” the TPM for
the motherboard. This is done through the BIOS, which can also be used to
enable TXT support. You then will need to “lock” the TPM in the firmware. This
is done through the provision utility provided by Intel.
A. Enabling the TPM in the BIOS
-
Enter the BIOS setup screen. You may do this either from the IPMI remote console or from the server directly using KVM. Reboot the system, and press the
key as the system boots until you reach the BIOS screen. -
You will be presented with the BIOS Setup main screen. Using your arrow keys, navigate to the “Advanced” tab. From there, navigate down and select the “CPU Configuration” option. Press
. -
You will then be taken to the CPU Configuration page. Using your arrow keys, navigate down to the “Intel Virtualization Technology” option, as shown below, and press
. If this item is not already enabled, select Enable and press . 
-
Once you have enabled virtualization support, press your
key until you are back to the “Advanced” tab. Navigate down to the “Trusted Computing” option and press .The Trusted Computing window will appear.
Note: By default, “SHA-1 PCR Bank” and “SHA-256 PCR Bank” are Enabled.
-
Disable “PH Randomization” and “TXT Support” only. Using the arrow keys, select each option, press the
key to select Disabled, and press the key again. -
Press the
key to bring you back to the “Advanced” tab options. Use the arrow keys to toggle to the “Save & Exit” tab. 
-
Use the arrow keys to select “Save Changes”. Press the
key.
B. Provisioning Intel TXT (Server)
Next, you will need to provision Intel TXT in the UEFI shell.
Note: If the TPM part number is AOM-TPM-9670V-S or AOM-TPM-9670HS, you do
not need to get the Intel® Provisioning Tool. Please go ahead and enable the
Intel TXT feature in the BIOS.
-
Select “UEFI: Built-in EFI Shell” in the BIOS. The system will boot into the Unified Extensible Firmware Interface (UEFI) with a list of available USB devices.
-
Each USB device has its own code. Type the code for the USB device that you want to use into the command line at the bottom of the screen. and press the
key.
Note: The device used for the purposes of this user guide had a code of fs0. Replace this code with the code that corresponds to your device. -
In the command line at the bottom of the screen, follow these steps below after typing “FS0”.
-
After the provisioning process has been completed, you will need to go back into the BIOS and enable “TXT Support”. To do this, type “exit” in the command line at the bottom of the screen and press the
key. 
C. Enabling TXT Support
The last step is enabling TXT Support in the BIOS and UEFI shell.
- Go back to the “Advanced” tab in the BIOS and enable Platform Hierarchy, Storage Hierarchy, Endorsement Hierarchy, PH Randomization, and TXT Support.
- Go back to the “Save & Exit” tab and select “UEFI: Built-in EFI Shell” in the BIOS. When the confirmation window appears, select
. 
- After Enabling TXT Support in the BIOS, you will need to run TXT in the UEFI shell. In the Command line at the bottom of the page, type “get- sec64_v2.0.11.efi -l sen -a” and press the
key. TXT support is now enabled. 
- To Exit from the TXT Environment, type “getsec64_v2.0.11.efi -l sexit” in the command line at the bottom of the screen and press the
key.
