Option Description
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 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’s 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
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.
Options Description
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. The 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 results in the
image Execution Information Table, but executes 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
option.
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.
