Well, from looking at the current pcic driver sources I can't see how a mapped-at-zero card could work with what we have. That would tend to imply to me that while they are supported by the CIS design, there ain't too many of them around. How far off the mark am I? And is there a decent, non-expensive, reference to the CIS structure anywhere? mike
