The VGA board is always enabled, but, VGA is defined by the number of pixels you have your computer display set at. For instance, if you go into Control Panel>display you will see what your pixels are set at. VGA is 640X480, XGA is 800X600 and SVGA is 1024X768. So if you change your pixels to 640X480 then you will have VGA.
