When i get to the screen for the Intergrated NIC I can go over to the area that highligts the options put that is it. How to I change the options. to OFF. I have tried everything from space to Enter to everykey i can thank of. U to change the postion of the options but nothing happens. Could some one give me a clue on how to change this option.
