The document I sent you from ADDI-DATA does show that the I/O map revision can be determined by reading the "Header EEPROM" at BAR1 + 0x00. This seems to verify Ian's comment about earlier versions of the board having a different mapping. As Ian already mentioned. It's probably best to leave the PCI bar resource mapping as it currently is. If anyone reports an issue it can be addressed later.
