Password Protection
The BIOS uses passwords to prevent unauthorized tampering with the system. Once secure mode
is entered, access to the system is allowed only after the correct password(s) has been entered.
Both user and supervisor passwords are supported by the BIOS. The user password cannot be set
unless a supervisor password has been set.
When set, a password can be cleared by changing it to a null string. Clearing the supervisor
password also clears the user password. Entering the user password permits modification of the
time, date, language, user password, and password on boot setup fields; other setup fields can be
modified only if the supervisor password is entered. The user password also allows the system to
boot, if secure boot is enabled.
If a wrong password is entered three times in a row, the BIOS stops validating passwords and the
BIOS security engine returns a failure for any further password validation attempt. If the user
enters three wrong passwords in a row during the boot sequence (i.e., when entering Setup), the
system is placed into a halt state. This feature makes is difficult to break the password by the “trial
and error” method.
