MEM C000h:xxxxh - 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. VBE(VESA BIOS Extensions) The common software interface for video cards providing support for high resolution and bit depth. v3.0 PROTECTED MODE INFORMATION BLOCK
Size:	20 BYTEs
Range:	starting at any byte within the first 32K of segment C000h


Format of 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. VBE(VESA BIOS Extensions) The common software interface for video cards providing support for high resolution and bit depth. 3.0 Protected ModeOne of the operating modes of the 80286 and higher Intel processors, in which addresses used by programs no longer correspond to physical addresses and the CPU enforces various protection mechanisms designed to prevent one program from disrupting other programs or the operating system.  See also Real Mode, Virtual-86 Mode. Information Block:
Offset	Size	Description	(Table M0127)
 00h  4 BYTEs	signature "PMID"
 04h	WORD	offset of protected-mode entry point within 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.
 06h	WORD	offset of protected-mode initialization entry point
 08h	WORD	selector for 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. data area emulation block
