BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and
who can boot the computer. A supervisor password and a user password can be set
for the BIOS Setup program and for booting 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 the supervisor mode.
• The user password gives restricted access to view and change Setup options in the
BIOS Setup program. This is the 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 password or the user password to access Setup. Users have access to
Setup respective to which password is entered.
• Setting the user password restricts who can boot the computer. The password
prompt will be displayed before the computer is booted. 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, and 0-9. Passwords may be up to
16 characters in length.
Table 45 shows the effects of setting the supervisor password and user password. This
table is for reference only and is not displayed on the screen.
