The tiny chip to the left of the Intel-branded processor is Lenovo ThinkPad X200 Intel ME source of the problem. The next hurdle was figuring out exactly what type of firmware chip I had in my laptop, because there are different SOIC clips for different types of chips, and the only way to find out which sized chip I had was to get the laptop and take it apart. New Atheros WiFi card installed.
Moving along, the BeagleBone had to be configured in a very particular way. This process took me a few hours over the course of two days.
The BeagleBone fits their requirements, the Pi does not, and they do not mention this. In general, it felt like I needed multiple degrees in computer science to make sense of their instructions on the first try. This can be a common plague of free software: That meant getting it on the network via Ethernet, and since my router is in Lenovo ThinkPad X200 Intel ME kitchen I set up shop there.
After soldering some wires to the SOC clip, I was finally ready to start flashing some Lenovo ThinkPad X200 Intel ME. Alternatively, if you are running libreboot already with the correct MAC address in your ROMdump it flashrom -r and read the first 6 bytes from position 0x or 0x in a hex editor or, rename it to factory.
Assuming that your libreboot image is named libreboot. For 16MiB flash chips: When you write-protect the flash chip, re-flashing is no longer possible unless you use dedicated external equipment, which also means disassembling the laptop.
The same equipment can also be used to remove the write-protection later on, if you choose to do so. Change them all to 0x0, then re-compile ich9gen. The next Lenovo ThinkPad X200 Intel ME you boot, the flash chip will be read-only in software hardware re-flashing will still work, which you will need for re-flashing the chip after write-protecting it, to clear the write protection or to flash yet another ROM image with write protection set in the descriptor.

These 2 regions could actually be separate files, but they are joined into 1 file in this case. The newly built ich9gen executable will be able to re-create the very same 12KiB file from scratch, based on the C structs, this time without the need for a factory.
You should now have a libreboot. It also sets all regions read-write. Generally, the following is true: ME firmware is not readable.
