Well your amazing support here is appreciated. Thanks very much for all the work you put in, I'm sure I speak for everyone. I'm trying to learn how to mod from some of help stickies here, if you would be able to give a short tutorial how to mod these Award/Pheonix BIOS's I'd be willing to help out.
My own thought is that it won't make any difference. If the BIOS code has changed with these betas then it's unlikely it will change back again if they ever become a proper release. It may just happen that after a period of testing they get released as final without any further work on them. These particular beta's are unofficial, that doesn't mean they are second rate, in fact by all accounts they are very good and most places are recommending to use them. Abit though may never release them as a final version. I don't know why 16b3 and 14b5 are proving difficult to mod, I've tried to find out, but it's beyond me! I'm grateful to have a modded BIOS in the first place, and will just have to be patient and hope a way to mod these latest two comes about. Anyway, it will give us something to look forward to!
