   Option	Description
   CPU AES-NI	Improves the speed of applications by performing encryption and decryption by using the Advanced Encryption Standard Instruction Set (AES-NI). The default value is Enabled.
   System Password	Sets the system password. The default value is Enabled and is read-only if the password jumper is not installed in the system.
   Setup Password	Sets the setup password. This option is read-only if the password jumper is not installed in the system.
   Password Status	Locks the system password. The default value is Unlocked.
   TPM Information	Indicates the type of Trusted Platform Module, if present.

   The following table provides information about the TPM 2.0 security information.

   Table 2. TPM 2.0 security informationThis table provides information about the TPM 2.0 security information.

   Option	Description
   TPM Information
   TPM Security	NOTE:The TPM menu is available only when the TPM module is installed. Enables you to control the reporting mode of the TPM. When set to Off, the presence of the TPM is not reported to the operating system. When set to On, the presence of the TPM is reported to the operating system. The default value for TPM Security is Off.
   	When TPM 2.0 is installed, the TPM Security option is set to On or Off. The default value is Off.
   TPM Information	Indicates the type of Trusted Platform Module, if present.
   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.
   TPM Advanced Settings	Specifies TPM Advanced Settings details.

   The following table provides information about the System Security details.

   Table 3. System Security detailsThis table provides information about the System Security details.

   Option	Description
   Intel(R) TXT	Enables you to set the Intel Trusted Execution Technology (TXT) option. Enabling the Intel TXT option requires that virtualization technology and TPM Security are enabled with Preboot measurements. The default value is Off. 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 the option is set to Disabled, BIOS disables both TME and MK-TME technology. When this option is set to Single Key, the BIOS enables the TME technology. When the option is set to Multiple Keys, BIOS enables the TME-MT technology. The default value is Disabled.
   TME Encryption Bypass	Allows the option to bypass the Intel Total Memory Encryption. The default value is Disabled.
   Intel(R) SGX	Enables you to set the Intel Software Guard Extension (SGX) option. To enable the   Intel SGX option, the following must be true: The processor must be SGX capable. Memory population must be compatible (minimum x8 identical DIMM1 to DIMM8 per CPU socket, not supported on persistent memory configuration), Memory operating mode must be set at optimizer mode. Memory encryption must be enabled. Node interleaving must be disabled. The default value is Off. When this option is to Off, BIOS disables the SGX technology. When this option is to On, BIOS enables the SGX technology.
   Power Button	Enables or disables the power button on the front of the system. The default value is Enabled.
   AC Power Recovery	Sets how the system behaves after AC power is restored to the system. The default value is Last. NOTE:Until iDRAC Root of Trust (RoT) is completed, host power-on occurs a minimum of 90 seconds after the AC applied.
   AC Power Recovery Delay	Sets the time delay for the system to power on after AC power is restored to the system. The default value is Immediate. When this option is set to Immediate, there is no delay for power-up. When this option is set to Random, the system creates a random delay for power-up. When this option is set to User Defined, the system delay time is manually configured.
   User Defined Delay (120s to 600s)	Sets the User Defined Delay option when the User Defined option for AC Power Recovery Delay is selected. The AC recovery time adds iDRAC Root of trust time (around 50 s).
   UEFI Variable Access	Provides varying degrees of securing UEFI variables. When set to Standard (the default), UEFI variables are accessible in the operating system per the UEFI specification. When set to Controlled, selected UEFI variables are protected in the environment. New UEFI boot entries are forced to the end of the current boot order.
   In-Band Manageability Interface	When set to Disabled, this setting hides the IPMI devices from the operating system for the following: the Management Engine (ME), HECI devices, and the system. Hiding the IPMI devices prevents the operating system from changing the ME power capping settings, and blocks access to all in-band management tools. All management functions should be done through out-of-band. The default value is Enabled. BIOS update requires HECI devices to be operational. DUP updates require the IPMI interface to be operational. This parameter must be set to   Enabled to avoid updating errors.
   SMM Security Mitigation	Enables or disables the UEFI SMM security mitigation protections. The default value is Disabled.
   Secure Boot	Enables Secure Boot, where the BIOS authenticates each preboot image by using the certificates in the Secure Boot Policy. The default value for Secure Boot is Disabled.
   Secure Boot Policy	When the Secure Boot policy is set to Standard, the BIOS uses the system manufacturer key and certificates to authenticate preboot images. When the Secure Boot policy is set to Custom, the BIOS uses the user-defined key and certificates. The default value for the Secure Boot policy is Standard.
   Secure Boot Mode	Configures how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).
   	If the current mode is set to Deployed Mode, the available options are User Mode and Deployed Mode. If the current mode is set to User Mode, the available options are User Mode, Audit Mode, and Deployed Mode.
   	Below are the details of different boot modes available in the Secure Boot Mode option. User Mode: In User Mode, PK must be installed, and BIOS performs signature verification on programmatic attempts to update policy objects. The BIOS allows unauthenticated programmatic transitions between modes. Audit Mode: In Audit Mode, PK is not present. BIOS does not authenticate programmatic update to the policy objects and transitions between modes. The BIOS performs a signature verification on preboot images. The results are logged in the image Execution Information Table, but runs the images whether they pass or fail verification. Audit Mode is useful for programmatic determination of a working set of policy objects. Deployed Mode: Deployed Mode is the most secure mode. In Deployed Mode, PK must be installed and the BIOS performs signature verification on programmatic attempts to update policy objects. Deployed Mode restricts the programmatic mode transitions.
   Secure Boot Policy Summary	Specifies the list of certificates and hashes that secure boot uses to authenticate images.
   Secure Boot Custom Policy Settings	Configures the Secure Boot Custom Policy. To enable this option, set the Secure Boot Policy to Custom option.
