It turns out that the one board which was working had correct strapping with the PCI Sync clock at 33MHz. A mix up in manufacturing allowed our other boards to be straped with a 16MHz clock. For those of you who don't know even if the PCI bus is in Asyncronous mode the Sync clock must be >= to the bus speed. In our case 33MHz. Thanks so much for the input, it is always the simple ones which are hard to find.
