Apologize for my repost as I found that I had my previous email sent without subscribing first to the mailing list so I failed to receive the reply in my inbox.
Hello awokd, can you please reply again here so I can reply to it? Sorry for the nuisance.

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
