These are the two VGA address ranges

02B0-02DF	Alternate VGA Video Display Adaptor assignment (secondary address)
03B0-03DF	EGA / VGA Video Display Adaptor, (Primary address)

Not sure yet how to control which one a VGA card responds to

This is a standard VGA register

it can disable the RAM response and move some of the IO
