ATI Radeon programming with XBIOS – tutorial

On BUS ERROR wiki I’ve published an article called “ATI Radeon programming with XBIOS”, which I promised last time when I showed my last video demonstration on this topic. Article is my personal comment to source code which accompanied the video. It shows how to use new XBIOS calls (or rather new VSetscreen() extensions) and exposes lack of important functionalities in current Radeon drivers and CTPCI firmware. So it will be not very nice all the time. ;)
If you are a programmer and you are curious about why there is still no games or demos which support ATI Radeon on Atari Falcon yet, only boring GEM applications, then have a good read. But before you start, get yourself a bucket of coffee, because it is pretty long. ;)
