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.
