INT 10 - VESA(Video Electronics Standards Association) An industry group which sets both hardware and software standards and recommendations. The term VESA is also used to denote compliance with the VESA SuperVGA BIOS Extensions, a standard set of video BIOS functions for accessing video modes of higher resolution than those defined by IBMInternational Busiuness Machines. SuperVGA BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. - GET VBE(VESA BIOS Extensions) The common software interface for video cards providing support for high resolution and bit depth./AF v1.0P DEVICE CONTEXT BUFFER {#idx4672}
