How would I in DJGPP do the following:?  I have browsed the allegro game
library but got nothing out of it (wayyyy too much code).  I can do the
following in 16-bit does apps, but DJGPP's 32-bit protected mode poses a
problem.  Links to the code or just replies with the code would certainly be
appreciated.

1.  get into different video modes (320x200 w/ 256 colors and more, 320x240
w/ 256 colors and more, 640x480 w/ 256 colors and more, etc.)?
2.  put a pixel in those modes (any difference in them...?)?
3.  get back into 80x25 text mode?
I'm unfamiliar with at&t style asm (plus I'm <beginner at intel style asm),
and even if I knew at&t style asm I wouldn't be able to do it since I think
32-bit protected mode getting into graphics are different than what I have
to do with turbo c++.  I hope that the putpixel routine is the fastest that
you know of, because that's the only one that really needs a lot of speed.
Thanks for all of your time.
