Right, firstly it WAS a corrupted download, fist I've ever had. Live
and learn!

Redownloaded, mounted as iso with lofiadm, upgraded live update to b40
version on DVD, bad move, got out of memory errors when allocating
slices for the new BE. So I downgrade LU to b33 and no problems
whatsoever, went like a dream!

Thanks for the help guys!!
