Hi,
I tested around with my board and to make it short it does not boot anymore. So the only way to get it working again is to hardware flash it.
On the libreboot website a beaglebone board is recommended to flash and there is also some documentation:
https://libreboot.org/docs/install/ga-g41m-es2l.html
"You can only externally reprogram one of the chips at a time, and you need to disable the chip that you’re not flashing, by connecting 3v3 to /CS of that chip, so you will actually need 2 test clips (you also need to connect GND on the chip that you’re disabling)."
What does connecting 3v3 means and what is /CS?
This board is hard to flash externally. I recommend desoldering both chips (the fastest way), be careful, you can break traces, when desoldering, do not force, if you force it when tin it is not hot enough, you may break traces when extracting. Default chips are unfriendly with flashing, you should buy new SPI chips with more space. WHen you have desoldered both chips, take new one and flash libreboot into it (chip space must to match with libreboot image size), when SPI chip is desoldered, maybe you need to connect 2 additional wires to V (PSU 3v wire), and these additional wires (2 wires, from SPU 3v, so in total you will have "3wires x 3v") connect to both NC when you flash the chip. You only need one chip, you do not need to solder backup chip.
Also, I recommend to buy quality cooler for CPU and Xeon x5460.
I don't have the equipment to desolder the chips.
Maybe it is cheaper to buy a new board :(
I already have a quality cooler for my Q9650.
