Hello Flashrom team,

As captioned. I read the flashrom man page and understand that one-time programmable memory may be out of scope of flashrom and hence the failure on my chip readings.

My goal is to make a backup of the chip before I put my motherboard into production and connect it to the internet. If my motherboard is hacked and content within the chip changed, I can easily roll back the chip to a known trustable state by flashing the backed up image back into the chip.

Can you please advise how I can achieve my goal? Should I go purchase a hardware flash programmer and mess with it (I don't have any electronic knowledge)? I searched the net and found "Bus Pirate", am I correct to say that it is a programmer/debugger that can talk "directly" to the chip? Would this possibly help in my case?

Motherboard                  : ASRock X300M-STX
CPU                          : AMD Ryzen 5600G
BIOS chip                    : Winbond W25Q128.w
"AMD fTPM switch" within BIOS: Disabled
Programmer used              : CH341a /w USB interface

Thank you for your time considering my questions. I hope you will have a good day.
Alan
