 8  The following things are still missing from this coreboot port:
 9  
10  - Extended HWM reporting
11  - Advanced LED control
12  - Advanced power configuration in S3

38  ### Internal programming
39  
40  Internal flashing is possible. The SPI flash can be accessed using [flashrom],
41  but you have to short the FDO pins located near the rear USB3 ports on the
42  motherboard using a jumper, to temporarily disable write protections while on the
43  stock firmware. Once the coreboot rom is flashed, one should remove the jumper.
44  
45  ### External programming
46  
47  External programming with an SPI adapter and [flashrom] does work, but it powers the
48  whole southbridge complex. You need to supply enough current through the programming adapter.
49  
50  If you want to use a SOIC pomona test clip, you have to cut the 2nd DRAM DIMM holder,
51  as otherwise there's not enough space near the flash.
