TPM2
Algorith
m
Selection
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

Option
Description
Intel(R) TXT
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.
Memory Encryption
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.
Intel(R) SGX
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.
SGX Package Info In-Band
