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.
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, the CPU Physical
Address Limit option must be disabled for selecting Multiple Keys option. This option is
set to Disabled by default.
