Hi i have a mother board with an on baord video card (A geforce 4 MX) the baord is an Epox baord with a Nvidia nforce2 chip set, EPoX 8RDA+. The baord has an AGP slot for a video card. I want to be abel to use both the onbaord car and the AGP card at the same time but when i plug in the AGP card the on board card seems to completely disapear (its not shown in device manager)

Does any one know how i can stop the onboard card from diaspearing??
