Using passwords
Using passwords helps prevent your computer from being used by others.
Once you set a password and enable it, a prompt appears on the screen
each time you power on the computer. Enter your password at the prompt.
The computer cannot be used unless you enter the correct password.
Make sure that only authorized individuals access your computer.
Establishing different kinds of passwords requires that other possible users
know the proper passwords in order to access your computer or your data.
As many as three different passwords can be used for your computer: the
Supervisor password, the User password, and the Hard disk drive (HDD)
password. When the Supervisor password is set, only the Supervisor
password entitles you full control of the computer.

Supervisor password
With a Supervisor password, you have full control of the computer.
When you enter the BIOS Setup Utility with a Supervisor password, you
are entitled to set all of the options.
ƒ User password
If a User password is set and Password on boot is set to Enabled, a
password prompt appears when you turn on the computer. Unauthorized
users cannot get access to configuration data. You can also use the User
password to enter the BIOS Setup Utility, but only a part of the options
can be set.
