3–8 BIOS Setup Program

The Security screen allows you to restrict access to the Setup

program by setting passwords for two different access modes:

• Administrative

• User

Administrative mode has full access to the Setup program. User

mode allows limited access to these setup options:

• system date and time change

• power management hot key

• user password change

• security hot key

• unattended start

You can set separate Administrative and User passwords, to limit

who can change critical setup values. The limitations depend on

whether either the Administrative or User passwords, or both are set.

To limit boot-up access to the system, set the User password. The

system asks for this password before booting. If only the

Administrative password is set, the system boots without requesting

a password. If both passwords are set, you can enter either password

to boot the system.
