Abstract
A display system conversion technique that provides text-mode (e.g., VGA mode) display capabilities to a computer system that lacks text-mode display hardware is disclosed. By using the display conversion technique, programs which assume or require text-mode display hardware can be made to operate properly on computer systems that lack such text-mode display hardware. According to one implementation, a display system for a computer system having an operating system, includes: a display device for displaying an image, a frame buffer for storing a bitmap of the image, a display driver for causing the bitmap to be forwarded to and displayed on the display device, and a text-mode-to-bitmap conversion system for converting text characters received from the operating system operating in a text-mode to the bitmap of the image which is stored in the frame buffer.
