Option Description
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 When Secure Boot policy is set to Standard, the BIOS uses the system manufacturer key and certificates to
Policy 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.

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:
• A password can have up to 32 characters.
• The password can contain the numbers 0 through 9.

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.
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.
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 and logs the results in the image
Execution Information Table, but approves the images whether they pass or fail
verification.
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.
