The following icons appear in this section:
Two Levels of Passwords
Both the Supervisor and the User icons configure password
support. If you use both, the Supervisor password must be set. If
this feature is enabled, you can select AMIBIOS. The setup
messages are in different languages. The default setting is English.
The system can be configured so that all users must enter a
password every time the system boots or when AMIBIOS Setup is
executed, using either or both the Supervisor or User password.
