I've applied to the ATI Developer Relations=20 program under the project I'm working on, maybe they'll see fit to give=20 me some manuals - I'm only looking for details on chips circa 9200,=20 nothing too recent. Until then, I've dug up Voodoo3 and Matrox G400 datasheets - I'll go=20 through the relevant code armed with these and see if I can figure=20 things out that way. I'm sure I'll have a question or two to ask you on=20 the way!
