Don't enable UEFI on this board, unfortunatelly this board will not, almost for sure, have a version for it.
UEFI is supported in Vista SP1 already, but not before anyway.
UEFI will eventually replace the good old BIOS, some manufaturers have already started to sample some boards with it, like MSI, but still not mainstream.
Intel, the project initiator, has it in workstation and server boards, but not in desktop boards. I asked them if there would be UEFI for BoneTrail but the answer was evasive as usual.
Another review is up for the DX48BT2, check it out in: http://www.hothardware.com/Articles/...US-ECS--Intel/
As usual, when it come to oc'ing everyone gets an headache. It takes time and patience, this baby needs a lot of attention first...
