I have seen things which make me suspect that among the undocumented bits of some of them lurk a DMA engine or two, but as far as I know the bits remain undocumented and thus unused. Pity, too, because it would make sense to be able to DMA stuff (either video RAM contents or for the more sophisticated boards higher-level stuff like drawing operations) from host memory to the framebuffer. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
