Hi, all, We port linux-2.2.12 to our mipsel evaluation board. We use Ali 1535D south bridge. Now our disk can work under PIO, I want to work using DMA. I do not know how many places I have to initialize. If someone knows, please help me. Thanks! Barry __________________________________________________ Do You Yahoo!?
