'Sup 'dawg? You're in the right place mate. Look at Post 1. the 3790 patch is under 'Tools' on RGN_Tool. There is a more detailed tut by turboccc in Post #77. Of course if you do want to convert to 34xx you should look back in the 37xx>34xx thread. But if you want to stay as 37 here is the right thread. I'm not able to say if you look dumb, but you don't sound it so far ...... Ask any dumb questions you want, we specialize in dumb answers.
