Vesa-bios-extension meaning

An earlier VESA programming interface for Super VGA cards. It provided a way for developers of DOS games and applications to query a graphics card for its capabilities and to set resolution and color depth directly. A VESA software driver was provided by the card or game vendor. As of VESA BIOS Extension (VBE) 2.0, the driver had to be implemented in the card's BIOS, and resolutions were selectable by pixels (640x480, 800x600, etc.), not just mode number.The Universal DriverSince the graphics card could be interrogated, it allowed for the development of a universal driver that asks for and then uses the commands that the card supports. Most VBE modes are outlined below. For more details, see PC display modes. See UniVBE.Mode no. Video(hex) Res.
