Is there someting in config space, or do you just > check the device's docs? I've checked the memory base registers. A memory base register return bit set to zero 0 and bit2/1 tell the width (00 = 32bit, 10 = 64bit). I don't know if this is a shure indicator. But there are cards that definitive can't without replacement. E.g. USB OHCI controllers are defined with 32bit DMA registers. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
