Super X13SCD-F User's Manual
Endorsement Hierarchy (Available when Security Device Support is set to Enabled)
Select Enabled for Endorsement Hierarchy support, which contains separate controls to
address privacy concerns because the primary keys in the hierarchy are certified by the
TPM key or by a manufacturer with restrictions on how an authentic TPM device that is
attached to an authentic platform can be accessed and used. A primary key can be encrypted
and certified with a certificate created by using TPM2_ActivateCredential, which allows
you to independently enable "flag, policy, and authorization values" without involving other
hierarchies. A user with privacy concerns can disable the endorsement hierarchy while still
using the storage hierarchy for TPM applications, permitting the platform software to use the
TPM. The options are Disabled and Enabled.
Physical Presence Spec Version
Use this feature to change what Physical Presence Interface (PPI) Spec Version the OS
should support. The options are 1.2 and 1.3.
TPM 2.0 InterfaceType
Use this feature to view the interface type of the TPM 2.0 device.
PH Randomization
Select Enabled for Platform Hierarchy (PH) Randomization support, which is used only during
the platform developmental stage. This feature cannot be enabled in the production platforms.
The options are Disabled and Enabled.
TXT Support
Select Enabled to enable Intel Trusted Execution Technology (TXT) support to enhance
system integrity and data security. The options are Disabled and Enabled.
Note 1: If this feature is set to Enabled, be sure to disable Device Function On-Hide
(EV DFX) support when it is present in the BIOS for the system to work properly.
Note 2: For more information on TPM, refer to the TPM manual at
micro.com/manuals/other/TPM.pdf.
