Where did you buy the system from? Whoever sold it to you should, at a minimum, give you a good start up program with all that information included

Even on vacation, we were open. I remember you now. You were the guy who called last week saying you didn't know we sold xfi's and wanted our tech support. I'm sure cotton can get you going
