Bios is easy but only make a single change at a time and then reboot. Write it down what you did. It's important when you make changes to the bios that you know exactly what you did where it is and how to undue it if problem come up so you can easily fix it without creating yet more problems. Bios is key to making a computer run best and by default lots of things are turned off because they have know way of knowing if your equipment can handle the new settings so they keep it turned off cause it creates problems for you. Like for instance Printers have a old low speed tranfer and a new (1995) highspeed tranfer. Guess what you cannot even buy a old slow tranfer printer anymore even if you tried but the bios is set to go the old slow way just incase, even today by default. So best to check the bios. Go here and read all about it. I also posted a link here not to long ago about tweaking XP for more speed. Look around for it.
