That is because the IBM standard was to support 2 monitors - one color and one
mono (at 0xb8000 and 0xb0000 if I remember correctly). If you put a CGA card
in as the 2nd card then the VGA card configures itself as a mono card and
uses the mono frame buffer address. If you replace the CGA card with an MDA
or HGC card then the VGA card will configure itself for color use.
