Ace,
When you boot your pc somewhere on the screen you will see something to the effect of "press this button for setup". Usually it's the Delete key but it could be different depending on your mainboard.
Once in the setup you're probably looking for "onboard peripherals" or "built-in" once again it's different for each mainboard but shouldn't be too hard to find.
Your mainboard manual ( you can download if you're like me and can't locate the original ) would be a good thing to have on hand.
Be careful in the dark forest of the BIOS,,there be dragons lurking that will render your pc inoperable.
Good luck,,cpthowdy
