Subject: How to map darkest to lightest in 256 color VGA?

  My VGA card (Video7 Fastwrite w/512K) does not have a 256 gray scale.  I'm
trying to map the 256 colors from darkest to lightest (000 -> 255) so I can
display a binary image file.  I've been using Ghostscript 2.0 but I'd like
to try it in color to see what it looks like.  When I try no mapping at all,
I can make out the image but the intensity to color numbering is way off.  It 
seems that if I could reorder them properly that the image would be clearer.

   I'm using INT 10 with the special modes mentioned in the Fastwrite manual
to write the dots to the screen (the image is 256 x 256 x 8).  Thanks for
the help!
