Amd Athlon XP@2.13ghz 512mb Ram 450watt psu Pheonix Award Bios v6.00pg This is a compaq pesario 6430nx. I just bought a nvidia 6800 and cant get it to work. My bios dosent have half the options that people are telling me about and i think thats why the card wont work. Im not sure if unshadowing it will help me any but will it give me more options? If anybody knows how to do it please tell me.
