Subject:	Allegro problem

I 'm experimenting some problems with allegro 2.2:

It's pretty simple, when I run the demo in 640x480 page flipping, the
lower half of the screen appears twice . So you never see the upper half
of the screen.
Then I tried with UniVBE 5.3 , that fixes that problem but some
filckering appears even with dirty rectangles technique. It seems like
UniVBE and vsync() aren't too happy of been together.

I have a Trident AGI 9440 card with 1 MB ram on a P5 133 machine.

BTW the fps almost duplicated with UNIVBE.

Hey Shawn, nice piece of work. If I could help in anyway to fix these
problems just e-mail me. I know well C, but I didn't even see your code
yet and I didn't do too much in VESA/SVGA programming either.
Fernando
