I have an aopen ax6l mobo (i know it's old) and an inno 3d 64 mb agp video card. I had an old pci video card and am trying to switch to the agp. After updating the bios and setting the init display option to agp, I cannot get the mobo to see the new agp card. It just sees the pci video card even though the agp is selected in the bios. What could the problem be ?
