Option Description

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.

● 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.

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

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.

A message prompts you to reenter the system password.

5. Reenter the system password, and click OK.

6. In the Setup Password field, type your setup password and press Enter or Tab.

A message prompts you to reenter the setup password.

7. Reenter the setup password, and click OK.

8. Press Esc to return to the System BIOS screen. Press Esc again.

A message prompts you to save the changes.

NOTE: Password protection does not take effect until the system reboots.

Using your system password to secure your system
