5.5 BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program and who can
boot the computer. A Supervisor and User password can be set for the BIOS Setup program and
for botting the computer, with the following restrictions:
• The Supervisor password gives unrestricted access to view and change all the Setup
options in the BIOS Setup program. This is Supervisor Mode.
• The User password gives restricted access to view and change Setup options in the BIOS
Setup program. This is User Mode.
• If only the Supervisor password is set, pressing the <Enter> key at the password prompt
of the BIOS Setup program allows the user restricted access to Setup.
• If both the Supervisor and User passwords are set, users can enter either the Supervisor
or User password to access Setup. Users have access to Setup regardless to which
password is used.
• Setting the User password restricts who can boot the computer. The password prompt
will be displayed before the computer boots. If only the Supervisor password is set, the
computer boots without asking for a password. If both passwords are set, the user can
enter either password to boot the computer.
• For enhanced security, use different passwords for the Supervisor and User passwords.
• Valid password characters are A-Z, a-z, 0-9, and special characters. Passwords may be up
to 20 characters in length.
• To clear a set password, enter a blank password after entering the existing password.
