    I've recently posted 2 programs that do what you ask. One's in
assembly and the other is in pure QB. The messages labeled "VGA SCREEN
FADER".

    If you can't find it, then do this:

    Out &h3c7, color:out &h3c8, color       '<--- out to BOTH !!!
    Red=inp(&h3c9):Green=inp(&h3c9):Blue=inp(&h3c9)

    Where "color" is the color you want to find(put it in a for/next
loop to find all of the RGB colors...).

    Have fun!

    P.S. I've recently seen that some people only OUT to &h3C7 when
loading or changing the DAC colors. THIS DOES NOT WORK ON SOME VGA'S!!
Out to both &h3C7 AND &h3C8!!

    Don't ask why it doesn't work on some computers when you only OUT to
the first port. I'm didn't make the darn things...
