I am using multiple PCI-6014 boards in several systems. One of the systems now fails to boot. By trial and error with parts from other sytems, I have determined that I have a PCI-6014 board which if I place it in any system, the system it is in will not boot. If I remove this particular PCI-6014 board, then the system will boot. These same systems will boot and operate properly with any of my other PCI-6014 boards installed as well.
