Hi Federico,

it seems like different versions of the firmware engage different write
protection mechanisms and your version requires either a small piece of
code in flashrom to disable the write protection or the ugly hack of
connection the respective pins to VDD. The problem is that deriving the
right commands for the board is not straight forward and no one
bothered to find them yet (it requires reverse engineering the firmware
files).

Hi Stefan,

thank you very much for your reply.
So I will see if to keep my motherboard as it is or to change it with a
different one.

Have an happy new year!
Cheers,

Federico
