Option
Description
TPM Information
TPM Security
Enables you to control the reporting mode of the TPM. The TPM Security option is set to Off by
default.
When TPM 2.0 is installed, the TPM Security option is set to On or Off. This option is set to Off by
default.
TPM Information
Displays the operational state of the TPM.
TPM Firmware
Indicates the firmware version of the TPM.
TPM Hierarcy
Enables, disables, or clears the storage and endorsement hierarchies. When set to Enabled, the storage
and endorsement hierarchies can be used.
When set to Disabled, the storage and endorsement hierarchies cannot be used.
When set to Clear, the storage and endorsement hierarchies are cleared of any values, and then reset to
Enabled.

NOTE:
The TPM menu is available only when the TPM module is installed.
When set to Enabled, allows the Operating System to bypass Physical Presence Interface
(PPI) prompts when issuing PPI Advanced Configuration and Power interface (ACPI)
provisioning operations.
When set to Enabled allows the Operating System to bypass Physical Presence Interface
(PPI) prompts when issuing PPI Advanced Configuration and Power Interface (ACPI) clear
operations.
Allows the user to change the cryptographic algorithms used in the Trusted Platform Module
(TPM). The available options are dependent on the TPM firmware.
To enable TPM2 Algorithm Selection, Intel(R) TXT technology must be disabled.
The TPM2 Algorithm Selection option supports SHA1, SHA128, SHA256, SHA512 and SM3
by detecting the TPM module. This option is set to SHA1 by default.
Description
Enables you to set the Intel Trusted Execution Technology (TXT) option. To enable
the Intel TXT option, virtualization technology and TPM Security must be enabled with
Pre-boot measurements for TPM 1.2 or set to On with SHA256 algorithm for TPM
2.0. This option is set to Off by default. It is set On for Secure Launch (Firmware
Protection) support on Windows 2022.
Enables or disables the Intel Total Memory Encryption (TME) and Multi-Tenant (Intel
TME-MT). When option is set to Disabled, BIOS disables both TME and MK-TME
technology. When option is set to Single Key BIOS enables the TME technology. When
option is set to Multiple Keys, BIOS enables the TME-MT technology. This option is set
to Disabled by default.
Enables you to set the Intel Software Guard Extension (SGX) option. To enable the Intel
SGX option, processor must be SGX capable, memory population must be compatible
(minimum x8 identical DIMM1 to DIMM8 per CPU socket, not support on persistent
memory configuration), memory operating mode must be set at optimizer mode, memory
encryption must be enabled and node interleaving must be disabled. This option is set to
Off by default. When this option is to Off, BIOS disables the SGX technology. When this
option is to On, BIOS enables the SGX technology.
Enables you to access the Intel Software Guard Extension (SGX) package info in-band
option. This option is set to Off by default.
Sets the PPMRR size.
