Hi Koller
	Thanks for you help , I'll try what you tell me tomorow , and sand
back the test result to you , but which PCI-IDE bridge will support DMA on
MPC8540 ? I wonder the bandwidth of IDE will be a bottleneck of my system
requirement .

Thanks a lot !

Try to turn off DMA. It doesn't work yet AFAIK.
I am using a PDC20269 on PCI on a MPC8540, too. See my .config file...
I didn't focus on this problem yet. Let me know if you get it going.

My board PM854 is similar to the MPC8540_ADS
