If you simply must set a BIOS password, know that if you lose it, you lose access to your machine until you drop $50-$200 to fix it. In order to set a BIOS password, you must first load your BIOS configuration. You load the configuration by pressing a key or combination of keys during the POST (Power-On Self-Test). The key you press varies but is usually Del, F2, or F8. If you look at the information displayed during the POST, you will see that it tells you what key to use (if you only see a power-on splash screen, press escape to remove that screen and show the POST information). Once you access the BIOS configuration, it is fairly easy to figure out how to set the password.
