We just put an Asus A8V deluxe motherboard in our computer and we also installed the ATI Radeon 9600se graphics agp socket card and now our computer is only recognizing the onboard card. How do we change the default after we already have installed everything. I cant see a bios graphics onboard disable and I cant even see where the Radeon graphics card is...it is plugged in and we have gone through the software install.
