Hey Riz! Cool to see you here.
The Kickstart boards for the 1000 that I'm aware of can use 3.1 with no issues at all. Have you tried putting it in there? I'll double check, but that's my recollection off the top of my head (update: I checked). I know for a fact that with
the one EzdineG designed 3.1 works just fine.
