Blocking access in BIOS

To block access to the computer boot or change BIOS settings, password protection system is used. This system is effective only until the sophisticated user will not go inside the system unit and turn off BIOS batteries. You may also have to produce these actions after you forget the password for access.

For setting passwords “Supervisor password” and “User Password” commands (Set Supervisor password and Set User Password) can be used, which are in the main menu of the BIOS settings . In some BIOS versions, these commands can be placed in the Security menu. The first command sets the password for the administrator, which has full access, and the second – the users with restricted access.
