ABSTRACT:
In a method and apparatus for displaying data on a video display that is controlled by a video controller, the video controller is coupled to a high-speed memory and a low-speed memory. The memories have separate data paths. A video address corresponding to a location on the video display is received. If a specified address bit is in a first state, then data is displayed from the high-speed memory. If the specified address bit is in a second state, then data is displayed from the low-speed memory. The specified address bit may be a high order address bit that is not utilized by a conventional VGA controller to transmit address information.
