There are so many revisions... who knows ! The "dual head" chips do like you said: one accel engine and 2 CRTCs & DACs. >So i suppose the you will need to use a trick similar to the matrox one to get >dual headed accelerated X to work. > >But could it be possible to block this in hardware, and thus force mirroring >only operation ? > >How many different rage 128 mobility are around anyway ? > >Friendly,
