Really?
AFAICS you have to register as a developer with ATI and "The acceptance
of Developer by ATI [...] is subject to approval by ATI in its sole
discretion". At least I don't see any downloadable hardware level
documentation at http://www.ati.com/developer/.
Maybe I just didn't look hard enough? BTW, I'd be mainly interested in
how to access 2D Accelerator functions, video overlay and DMA, so if you
could give me some pointer on how to obtain documentation on that for
radeon 8500 or rage128 pro class cards, it would be very nice.
I have to admit I did not try registering yet, because it seemed to much
of a hassle for "I just like to have the documentation for my hardware"
and to me it seems doubtfull I would be accepted just for that reason.
