If you need to stick and turn the ignition key for the car to work, would that mean what the car runs on the key? I like what you and other sibling just regurgitate Wiki content. As another sibling properly notes - it run in a protected mode and had it's own drivers. It used DOS as a mere bootloader. Is your favourite Linux distro just a shell on top of GRUB? Please, educate yourself about this part and don't just copy-paste stuff someone managed to butt in Wiki article.
