Forgot about the refresh ones, you're correct they do need to be running V 2.0. You'd have thought most boards will be shipping with it now, but it's not that much of a headache to do it through the IPMI. Once I'd contacted them via the SUM request page, I'd got a response and a product key emailed the following day.
Hopefully I am lucky enough to get one with 2.0. Do I need to run a supported CPU to do a bios upgrade through IPMI or will it function without a cpu installed (I am guessing it needs a cpu)? I hope I don't need to go out an buy a cheap pentium. :(
