Try using the VESA drivers or the MACH64 driver when selecting your graphics
mode in Allegro. You could try getting Display Doctor from Scitech and see
if that helps. Also make sure you have called set_color_depth otherwise it
will default to 8-bit colour anyway! On my ATI XPERT with the Mach 64
driver, I can get 24-bit colour at 1024x768. In Windows I run 800x600 with
32-bit colour.

I've found that the drivers cannot get a mach 64 up to 32-bit colour. Has
anyone else found this?
