The problem is the locked ME region as quoted above. We are working on unlocking it, but intel does not provide us any documentation so please do not expect a solution soon.
Can you please tell us which Supermicro board that is so that i can add it to our list of unsupported boards in the meantime?
I can't, it's a custom(?) board with DMI info et al stripped and replaced.
OK
Why this ME region is important? It doesn't overlap with BIOS region.
Alexey, who know approximately nothing about BIOS internals
The ME region contains the firmware for an embedded controller (EC) in the chipset. It is used for fan control and a number of other things and also has access to basically everything the CPU has access to. The interaction between the BIOS with this EC is not documented and it is theoretically possible that updating the BIOS alone without updating the ME firmware before would brick the PC. Flashrom plays safe and disables writes if it detects that we can not write to the ME region.
