I'm not exactly sure what your problems are, but maybe this helps you achieve what you want. Firstly, 0xf 0000 0000 is the 36 bit physical address. This address is mapped by the driver via ioremap() into a 32 bit virtual address. Now, I think there are three macros for the PCMCIA memory regions (at least there were for the Au1100), which you can ioremap() separately. Now, what gave me most trouble where two other things that needed to be done for my board (they might be different for you): 1. configure the static bus controller This mainly means selecting the right timing parameters and switching the right bits on and off. You definitely need to read the programmer's handbook from AMD/Alchemy. 2. turn on power In my case, power on and card detect were wired to some GPIO pins, so I had to switch them to the right level. This might require additional configuration in advance, too, but you can check the results using a simple voltmeter. However: The DB boards are generally supported by Linux, so I wonder why you need to do anything at all. Uli
