- I'm trying to modify the values of the VGA's DAC registers but I'm having
- no luck. I first tried directly manipulating them via _outp's and that
- worked a little. But it didn't affect all of the DACs for some reason. And
- I'm sure I was writing to all 768 of them. So I decided to try to do it the
- nice way. Of course, I have no documentation except for the header files and
- I discovered a real problem. The VioSetState call can take 6 different
- structures in it's first parameter, 4 of which are the same size? There is
- an element of the structure labeled Type. I suppose that this element tells
- OS/2 which structure it is getting, but I have no idea what to set this to
- for OS/2 to realize that I am sending it a VIOCOLORREG structure.
-
- HOW DO I DO THIS?
-
- Sorry about the yelling, but I really would like to be able to find some
- docs on this stuff. The book supply in my are totally SUCKS.
-
- Thanks for the help
