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

Policy

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

Enables you to configure how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).

Mode

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

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, ("), (+), (,), (-), (.), (/), (;), ([), (\), (]), (`).

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. BIOS also 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.
