What board (model) are you talking about? You may be able to dump your ME firmware using Flash Programming Tool only if your Flash Descriptor is unlocked. Either way, it doesn’t matter. You should not include your latest dumped ME firmware at the BIOS mod as it may cause issues to other users due to system specific ME Initialization Data leftovers. Also, even if you follow the linked guide and include a configured w/o initialization data ME firmware inside your BIOS/SPI mod, other people won’t be able to update to it if their flash descriptors are locked because the CPU/BIOS wouldn’t have Read/Write access to the ME Region with such a configuration. Assuming you only have the BIOS region (usually laptop manufacturers do that), aside from ME, you need the Flash Descriptor and possibly GbE and PDR. These can be dumped and just added with no issues but yet again, if the recipient system’s flash descriptor is locked, the Flash Descriptor, GbE & ME regions won’t get updated due to lack of read/write access.
