Option Description
Deactivate, the TPM is disabled and deactivated. When set to Clear, all the contents of
the TPM are cleared. This option is set to None by default.
When TPM 2.0 is installed, the TPM Security option is set to On or O. This option is set to O by default.
TPM 2.0 security information
TPM Information Changes the operational state of the TPM. This option is set to No Change by default.
TPM Firmware Indicates the rmware version of the TPM.
TPM Hierarcy Enable, disable, or clear 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.
Intel(R) TXT Enables or disables 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. This option is set to O
by default.
When TPM 2.0 is installed, TPM 2 Algorithm option is available. It enables you to select a hash algorithm from
those supported by the TPM (SHA1, SHA256). TPM 2 Algorithm option must be set to SHA256, to enable TXT.
Power Button Enables or disables the power button on the front of the system. This option is set to Enabled by default.
AC Power Recovery Sets how the system behaves after AC power is restored to the system. This option is set to Last by default.
AC Power Recovery
Delay
Sets the time delay for the system to power up after AC power is restored to the system. This option is set to
Immediate by default.
User Dened Delay
(60 s to 240 s)
Sets the User Dened Delay option when the User Dened option for AC Power Recovery Delay is selected.
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 specication. When set to Controlled, selected UEFI variables are
protected in the environment and new UEFI boot entries are forced to be at the end of the current boot order.
In-Band
Manageability
Interface
When set to Disabled, this setting will hide the Management Engine's (ME), HECI devices, and the system's IPMI
devices from the operating system. This prevents the operating system from changing the ME power capping
settings, and blocks access to all in-band management tools. All management should be managed through out-of-
band. This option is set to Enabled by default.
NOTE: BIOS update requires HECI devices to be operational and DUP updates require IPMI interface to
be operational. This setting needs to be set to Enabled to avoid updating errors.
Secure Boot Enables Secure Boot, where the BIOS authenticates each pre-boot image by using the certicates in the Secure
Boot Policy. Secure Boot is set to Disabled by default.
Secure Boot Policy When Secure Boot policy is set to Standard, the BIOS uses the system manufacturer’s key and certicates to
authenticate pre-boot images. When Secure Boot policy is set to Custom, the BIOS uses the user-dened key and
certicates. Secure Boot policy is set to Standard by default.
Secure Boot Mode Congures 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.
