Having mostly completed assemby of my system, I now want to change the video from the "standard vga" default to my AGP ATI Ultra 128 card. Do I first delete the other driver (adapter) or??? I have the DELL driver disk appropriate to the AGP card. When I follow the install it says there is a conflict with other installed display. USE ASUS A7V8X-x, Win 98 SE and as stated an ATI RAGE 128 Ultra video card. I have tried using the ADD/REMOVE Hardware option.
