When a computer is powered on, the Basic Input Output System (BIOS) begins to run immediately. Users can change the settings of the BIOS so that it will prompt the user for a password whenever they open the system. This will make sure that the user is authorized to access the computer even before the Operating System is loaded.
The user first has to reboot the PC. A succession of diagnostics will flash on the screen and a message that says “hit the ‘DEL’ key to enter the BIOS setup program” will appear at the bottom.
If the Del key is pressed, a menu screen will pop up. Two options will be presented: ‘Supervisor Password’ and ‘User Password’.
Different versions of the BIOS program have varying features. Some versions may not even have the password feature.
Choosing a Secure Password
Choose the ‘User Password’ option. There will be instructions to choose a password that will not exceed eight characters. It is better to use all eight characters and to keep things as random as possible. Key in the characters you have chosen.
Security experts advise a string of random letters and numbers. This will make it harder for others to guess the password. Some of the most common passwords used are either common or related to the user’s personal information. This is discouraged by experts because these would be easy to guess.
Once the password has been typed in, BIOS will ask the user to retype it for validation. The settings of the system to can be changed so that it will request a password whenever BIOS begins to run.
Choose the ‘BIOS FEATURES SETUP’ link to be directed to another menu. In that menu, click on the password check link. Change the settings of the password to ‘Always’.
Return to the main menu. Save the changes and exit setup. Restart the computer to check if the BIOS prompts for a password when it is started.
