I have a rev 4.2 motherboard and there is a spot labeled J102, but there isn't any jumper there, just a pair of solder patches where I would expect it to be installed. Looking from the top of the motherboard it looks as if the patches are unconnected, which is why I was wondering if there was a difference. If there isn't a difference between revisions I expect that there is a connection of some sort on the bottom of the motherboard where I can't see it without a bit more work.
