Well it wasn't on there it was on the back of the box it came in! I checked out amdmb.com and people were going crazy trying to figure it out...seems it's not always in the same place...i.e. it can be where you said, where i said, and also someone said inside cover of there manual!?!? I stopped reading so i didn't see if there any more, but kinda makes ya wonder what's going on!
