[comp.lang.pascal] VGA Programming..

Greetings,

Well, I think I've exhausted all the "direct" approaches to solving
my problem, so I'll try the "brute force" method.

I recently found a couple of no-frills GIF viewers on the "grape"
archive site in the file "gifsrc.arc".  They were written by Jim
Griebel and for my EGA needs I was able to hack one of them a bit to
write a plain ASCII file with the actual numerical values for each
pixel (0=black, 1=blue,..., 15=white) of the GIF. These programs
are written in Turbo Pascal 4.0.

The programs work for EGA only, so of course, now I have been 
asked to do the same thing with VGA.  Not having any background
in programming VGA graphics, I have found out that VGA is quite a 
different animal...(than EGA).  I've sent msgs to "grape" asking
for info; they don't have any..I've got Richard Wilton's book
"Programmer's Guide to PC & PS/2 Video Systems" and I can't make
heads or tails out it..

The purpose of this post, then, is twofold: 

Jim Griebel, if you're reading this, please contact me, or if anyone 
has any info on VGA programming ie., which registers take what values,
etc.. please email.


thank you..
