You are correct, there's no such thing as PCI GART on the mach64. From memory, the only difference between AGP and PCI DMA scatter-gather tables is you need to set a bit somewhere to specify the pages are AGP memory, when required. Other than that, the DMA mechanism is the same, from the driver's point of view. As far as I can remember, anyway :-) -- Gareth _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
