33 Usage Note
34 ----------
35
36 Limit register locations on Intel boards with
37 build date 04/03/13 do not match the register
38 datasheet. Nuvoton confirms that Intel uses a
39 with different register addresses. The specifi
40 firmware is held under NDA by Nuvoton and Inte
41 to the public.
42
43 Some of the register locations can be reverse
44 well hidden. Given this, writing any values fr
45 considered too risky with this firmware and ha
46 must all be written from the BIOS.
