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

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