It isn't Allegro... You will see this with any graphics library you use. 
The standard vga modes have a border around the edge that is color 0.  I
don't know why, but that's the way it works.  The only thing I can tell you
is to keep color 0 to black, it's a pain, but it's the only way I've ever
seen to stop it from bugging the hell out of the user of the program. 
Sorry, that's probably not what you wanted to hear.
