At least it doesn't in my case. Perhaps your VGA card isn't running in 16-bit mode anyway. I have seen some cases where the VGA card wouldn't kick into 16-bit mode no matter how few cards were installed in the system. Try this. Run your VGA card's diagnostics with the MDA card in and out. Most will tell you if the card is running in 16 or 8 bit mode. If it is running in 8 bit mode, certain operations WILL be slower. Tests on my system for graphics intensive applications show about a 32% dip in performance with an MDA present. Robert F. Nee
