dunno if they will hex - I know most motherboards that are compatible have already had new BIOSes released. Its VERY doubtful however you will recieve a new motherboard with the latest BIOS so i'd hazard a guess at no it won't work until the BIOS has been updated (maybe put in a special request to whoever you buy your mainbard from - i.e. It MUST be thuban compatible BEFORE shipping).
