I'm not a big Allegro user, but my guess would be: whatever your hardware drivers support *for a DOS application*. I.e. the crucial piece is the VESA Video BIOS Extension (VBE) support of your graphics card, and how much of it is made accessible by its drivers. This area of driver support tends to be quite crappy these days, but you may have pulled a lucky lot. > I had, from the horror stories, expected to be limited to ancient > VGA modes, but I was able to get 1024x768x256 also.

Truecolor may still be available in the shape of 32bpp modes --- 24bpp is just too much of a hassle these days, given that all the modern cards have much more memory on board than even 2000x2000x32bpp could ever use. -- Hans-Bernhard Broeker (broeker AT physik DOT rwth-aachen DOT de) Even if all the snow were burnt, ashes would remain.
