1.      Introduction

        The program GAMMA.EXE enables or disables the option to use
        the color lookup table at VESA BIOS graphics modes with 15, 16
        and 24bpp (bit per pixel). These modes are direct color modes.

        The first call of GAMMA.EXE enables the option. After a
        VESA BIOS direct color mode is initialised, you can change the
        displayed color via programming the color lookup table. Now the
        VESA-call "Return Super VGA mode information" returns "Color ramp
        programmable".

        To disable the gamma correction again, you have to call GAMMA.EXE
        a second time. Now the VESA-call "Return Super VGA mode
        information" will return "Color ramp fixed".
