I can't seem to find a clear answer on this. 1. What tool do i use to verify what version of SLIC is in my bios. Mine came with vista a long time ago and has activated windows 7. 2. What is required to convert SLIC 2.0 to 2.1? 3. Am I correct in that the only difference in 2.0 and 2.1 is a few bytes within the bios labeling it which ever version?
