Supervisor/User Password Setting
You can set either supervisor or user password, or both of then. The
differences between are:
supervisor password : can enter and change the options of the setup
menus.
user password : just can only enter but do not have the right to
change the options of the setup menus. When you select this function,
the following message will appear at the center of the screen to assist
you in creating a password.
ENTER PASSWORD:
Type the password, up to eight characters in length, and press <Enter>.
The password typed now will clear any previously entered password
from CMOS memory. You will be asked to confirm the password.
Type the password again and press <Enter>. You may also press
<Esc> to abort the selection and not enter a password.
To disable a password, just press <Enter> when you are prompted to
enter the password. A message will confirm the password will be
disabled. Once the password is disabled, the system will boot and you
can enter Setup freely.
PASSWORD DISABLED.
When a password has been enabled, you will be prompted to enter it
every time you try to enter Setup. This prevents an unauthorized person
from changing any part of your system configuration.
Additionally, when a password is enabled, you can also require the
BIOS to request a password every time your system is rebooted. This
would prevent unauthorized use of your computer.
You determine when the password is required within the BIOS
Features Setup Menu and its Security option. If the Security option is
set to “System”, the password will be required both at boot and at entry
to Setup. If set to “Setup”, prompting only occurs when trying to enter
Setup.
