1.  svga256.bgi - This file replaces the file egavga.bgi 

2.  svga256.h - The include file that comes with svga256.bgi.
    You should include it in the file example.c and video.c.

3.  video.c - This file contains routines for initialization of the 
    graphic screen and colors.
    
    You do not have to fully understand these routines.
    The only important routine here for you is InitPalette().
    This routine determines the 256 colors which the screen will be
    able to display.

    In the file video.c the routine creates 64 different gray levels and
    use them for 256 colors.
    
    The color value 0 (when used with putpixel()) refers to BLACK, while
    255 refers to WHITE.    

4.  video.h - a header file for video.c

5.  example.c - an example of how a program should use the functions in the
    file video.c



Compilation:
------------

In order to compile and run example.c (or your C program), 
you should create a project in the 
Turbo-C environment and compile example.c along with video.c. Dont forget
to place svga256.bgi in the directory where you compile.



NOTE: the program may not be working on your pc's at home, since the
      svga driver (as it is defined now) may need a larger screen
      memory than you have. However, it works in the university.
