I was selected as a Host, so I have a free "Signature" copy of Ultimate winging it's way to me. I will of course not be having a party! I think some sort of death in the family may prevent it! Anyhoo, I already have the RTM installed and have a modded BIOS and am fully activated and working well. Should I sell my copy, install it, just put in the serial for it and active on my existing install? I suspect the media *should* be the same as the RTM so shall I just unmod my bios and active with valid serial do you people think?
