The newer version of that board had a completely revamped bus interface vhdl module, and also worked. I did not analyze the problem in depth, but I think the problem related to timing of the WRITE/ signal to the strobe, it may have been going away too soon. I latched WRITE/ when recognizing the strobe and it fixed the problem.
So, the D510MO has a subtle difference in timing of (I think) WRITE/ that never showed up on other motherboards. It is possible that differences in cables could make it work in some configurations and not others.
