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 any of the characters in the ASCII character set.

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.

Description

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.

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.

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.
