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. XGA(Extended Graphics Array) 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. Extensions - RETURN XGA(Extended Graphics Array) MODE INFORMATION
	AX = 4E02h
	CX = Video mode
	DX = XGA(Extended Graphics Array) handle
	ES:DI -> 256 byte buffer for mode information (see #00073)
Return: AL = 4Eh if function supported
	AH = status
	    00h	 function successful
	    else error code
