There are no daX devices at all, and the adaX devices that are listed are the hard drives that are going to be used for storage.
And yes, as I mentioned above I was able to boot from the USB using FreeBSD 9.2, thus indicating FreeNAS specific issue. I also had no issue getting NAS4Free 9.2 to boot from it, and I've been playing around with that as it offers virtually the same features as FreeNAS. If I really played around with it, I could probably get it to boot but at this point I don't see much point in putting in the effort.
I have no criticisms of your help and suggestions, in fact they're appreciated.
