Option In-Band Manageability Interface Description When set to Disabled, this setting hides 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-ofband. 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 certificates 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 key and certificates to authenticate pre-boot images. When Secure Boot policy is set to Custom, the BIOS uses the user-defined key and certificates. Secure Boot policy is set to Standard by default. Secure Boot Mode Enables you to configure 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. Options User Mode Description In User Mode, PK must be installed, and BIOS performs signature verification on programmatic attempts to update policy objects. BIOS allows unauthenticated programmatic transitions between modes. Audit Mode In Audit mode, PK is not present. BIOS does not authenticate programmatic updates to the policy objects, and transitions between modes. Audit Mode is useful for programmatically determining a working set of policy objects. BIOS performs signature verification on pre-boot images. BIOS also logs the results in the image Execution Information Table, but approves the images whether they pass or fail verification. 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 Secure Boot Custom Policy Settings Specifies the list of certificates and hashes that secure boot uses to authenticate images. Configures the Secure Boot Custom Policy. To enable this option, set the Secure Boot Policy to Custom. Creating a system and setup password Prerequisites Ensure that the password jumper is enabled. The password jumper enables or disables the system password and setup password features. For more information, see the System board jumper settings section. NOTE: If the password jumper setting is disabled, the existing system password and setup password are deleted and you need not provide the system password to boot the system. Steps 1. To enter System Setup, press F2 immediately after turning on or rebooting your system. 2. On the System Setup Main Menu screen, click System BIOS > System Security. 3. On the System Security screen, verify that Password Status is set to Unlocked. 4. In the System Password field, type your system password, and press Enter or Tab. Use the following guidelines to assign the system password: 52 Pre-operating system management applications
