BIOS Password & Write Protection
A BIOS password protects the BIOS setup program from unauthorized access. This ensures that
users cannot change the system configuration without authorization. With an assigned BIOS pass-
word, the BIOS prompts the user for a password on a setup entry. If the password entered is wrong,
the BIOS setup program will not launch.
The BIOS uses encryption for the password.
The BIOS password is case sensitive with a minimum of 3 characters and a maximum of 20 charac-
ters. Once a BIOS password has been assigned, the BIOS activates the grayed out BIOS Update and
Write Protection option. If this option is set to enabled, only authorized users (users with the correct
password) can update the BIOS. With the BIOS password protection and the BIOS update and write
protection, the system configuration is completely secured. If the BIOS is password protected, you
cannot change the configuration of an end application without the correct password.
