program. Unauthorized users cannot get access to conguration data.

that computer has set a power-on password. The supervisor password overrides the power-on password.

have the supervisor password:
– Deleting the power-on password
– Changing or deleting the supervisor password
– Enabling or disabling the Wake on LAN feature
