You can set either supervisor or user password, or both of them. 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.
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 is confirmed and the password will be
disabled. Once the password is disabled, the system will boot and you
can enter Setup freely.
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 (see Section 3). 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.
