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 passwords might be needed for your computer: the Supervisor password, the User Password, and the hard-disk drive (HDD) password. When passwords are set, only the Supervisor password entitles you full control of the computer. • User password If a user password is set and Password on boot is 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 BIOS Setup Utility, but only a part of the options can be set. • Supervisor password With a Supervisor password, you can get full control of the computer. It also can be used as a power-on password, the same as the User password. Also, when you enter the BIOS Setup Utility with a Supervisor password, you are entitled to set all of the options. The Supervisor password overrides the User password. • Hard disk (HDD) passwords Once an HDD password is set, you need to enter it to get access to the hard disk. You can set the HDD password through either the User Only selection or the User + Master selection in the BIOS Setup Utility. 44
