I think that Allegro isn`t the solution of my problem. Allegro is only a
library and so with Allegro I can`t do what I want. If I have to do some
effects that Allegro doesn`t support?

I think that Allegro is useful only to develop shareware applications,
but if you want to KICK ASSES (like a great game or a demo) you have to
implement yourself your procedures.

Thank

P.S.: The answer to my problem was to use the dpmi feature
__dpmi_segment_to_descriptor(0xA000);

P.S.S.: I have tryed Allegro on a 486DX66 and it worked very badly. Then
I have written my own procedures and the old 486 seemed much more
faster. What a joke!

Disgusted.
