Hi igor and Greg. It was my understanding that the coordinates are what you are supposed to use anyway. In fact, I think I remember trying sr0 and maybe some others that didn't work. I think Greg is simply referring to the output of dmesg; type dmesg, though probably what you want would be more toward the end. If you do dmesg > dmesg.txt, then you can look at the file instead of going through the whole thing.
