Abstract
A computer display system and method is disclosed which allows a display controller in the display system to use a block of system memory rather than a dedicated frame buffer for display modes that do not require the bandwidth or the memory size of a dedicated frame buffer. The display system of the present invention includes an optional dedicated frame buffer to allow the display controller to support display modes that require the performance of the dedicated frame buffer, while retaining the capability to use system memory as a frame buffer for display modes that would only partially use the dedicated frame buffer.
