Thank you Jolly for your HCL report, which is now part of this [pull request](2021-08-22_new_reports by SvenSemmler · Pull Request #92 · QubesOS/qubes-hcl · GitHub) and will be visible on the website soon!
... you guys make me wanna go out and get a X220 just for the fun of it. 
It definitely seems to be one of the most popular Qubes OS machines out there.

Hi Jolly, could you please give a complete manual on this setup?
How to make the heads firmware, how to flash it (ME will stop you from using flashrom -p internal).
Some SPI programming experiments with raspi-pi were not successfull at least for me. It seems
that the unpowered chipset of the computer pulls the data to ground and eats 3.3V so the programmer
has no power to live.
A complete tutorial to set this up would be cool. And if you make a video, better than nothing.
Thanks in advance
Ludwig
