When the 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.
You first have to reboot your PC. A succession of diagnostics will flash on the screen and a message that says “hit the
key to enter the BIOS setup program” will appear at the bottom.
If you press the Del key, a menu will pop up. You will be presented with two options: ‘Supervisor Password’ and ‘User Password’.
Your version of the BIOS program might have different features. Furthermore, your BIOS might not even have the password feature.
Choosing a Secure Password
Choose the ‘User Password’ option. You will be instructed to choose a password that will not exceed eight characters. Use all eight characters and try to keep things as random as possible. Key in the characters you have chosen.
According to security experts, a string of random letters and numbers should be used. This will make it harder for others to guess your password. Some of the most common passwords used are either common or related to the user’s personal information. These are discouraged by experts because they would be easy to guess.
Once you’ve typed in your password, BIOS will ask you to retype it for validation. You can change the settings of the system to request a password whenever BIOS begins to run. Choose the ‘BIOS FEATURES SETUP’ link and you will 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 runs.
