Internal programming

The SPI flash can be accessed using flashrom.

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.
