After trying to order the correct replacement PCB, I learned that each PCB has a unique identifier in the BIOS/Ram. It is therefore necessary to remove the BIOS from the broken PCB and attach it to the new/replacement PCB.  After much research, I found this nifty company in Canada who offers this service free of charge included in the purchase price of the PCB. I now sent off the broken PCB to meet my order in Canada.
