 Due to minor board changes (but still, they are changes), the motherboard
 ID will be incremented.

 This change will be delayed until the necessary software changes have been
 made, tested, and communicated to Quanta.  Quanta would like to make the
 change ASAP.

 The new ID (C3) will be (5/8) / 3VPCU =2.06V.
 R535 will stay as 10K.  R534 will change to 6.04K.

 The motherboard changes are mainly replacement of 0 ohm resistors with
 traces.   A resistor was also added to improve the robustness of the
 external microphone input.
