Ah OK I get your point now. You were originally referring to a NuBus to _IDE_ emulation layer, which sounds a little bit strange to me :) On the other hand I feel that NuBus itself is supported well enough in Linux 2.4 already. > as for DMA on a 1400... it SEEMS that each individual controller > supports DMA, even though I can't seem to get linux to realize that, but > it may be because of the bus design???

Thanks for sharing this piece of information. Can you provide a list of links or pointers to relevant specs, please? Thanks.
