But if all else fails, you won't do any harm to anything to just keep trying every combination of pins until you hit on the right ones. I've had to do that in the past, and I got them all in the end.
I do have Everest installed and it does not give any information about the Motherboard except "Compaq pc",I will have to follow your suggestion of trying different combinations and see what I come up with,thanks a lot, I will post back with the results later.
