Internal programming
TODO: investigate
The board has two jumpers that might be relevant: FDO (Flash Descriptor Override) and BB (?).
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.

SuperIO
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.
