Reverse Engineering an ATI Miniport Driver
OK, I decided to hold off on the Intel drivers, and instead go straight for the hard part. If I can do this then the Intel stuff will be easy, and I'll be well on my way to getting something started. So I downloaded a miniport driver for my Rage P/M Mobility AGP 2x card. I have disassembled the 70kb file and am wading through all of the defined miniport interfaces to examine how the device works. I'm trying to approximately rewrite the thing in Java as I go, but it's pretty messy-- there are at least 267 functions. It's just complex enough to be a total pain, but barely easy enough for me to attempt it. On the plus side, the driver I got appears to support many ATI display cards, so the end product might actually be useful to someone else.
