Chapter 2. Using your computer

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.
Two passwords might be needed for your computer: the Supervisor
password, and the User 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 can get 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, you can also use the User password to enter the
BIOS Setup Utility, but only a part of the options can be set. User
password can not be set if Supervisor password is not set.
