Option Description
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 Description
User Mode
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
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.
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.
● Only the following special characters are allowed: space, (”), (+), (,), (-), (.), (/), (;), ([), (\), (]), (`).
A message prompts you to reenter the system password.
5. Reenter the system password, and click OK.
