Internal programming

Internal flashing is possible. The SPI flash can be accessed using flashrom, but you have to short the FDO pins located near the rear USB3 ports on the motherboard using a jumper, to temporarily disable write protections while on the stock firmware. Once the coreboot rom is flashed, one should remove the jumper.

External programming

External programming with an SPI adapter and flashrom does work, but it powers the whole southbridge complex. You need to supply enough current through the programming adapter.

If you want to use a SOIC pomona test clip, you have to cut the 2nd DRAM DIMM holder, as otherwise there’s not enough space near the flash.
