  28 ### Internal programming
  29
  30 Internal programming is possible. Shorting the Flash Descriptor Override
  31 (FDO) jumper bypasses all write protections.
  32
  33 ### External programming
  34
  35 Remove the lid. The flash chip can be found on the edge opposite to the CPU.
  36 There is a spot for a "ROM RCVRY" header next to the flash chip but it is
  37 unpopulated. If you don't feel like using a clip, you can easily solder
  38 a standard pin header there yourself and use it for programming.
  39
  40 Programming powers some parts of the board. Programming when
  41 Wake on LAN is active works great.

  61 This board has a Nuvoton NPCD379 SuperIO chip. Fan speed and PS/2 keyboard work
  62 fine using coreboot's existing code for :doc:`../../superio/nuvoton/npcd378`.
