Hi Anastasia,
I looked at the information in:
> https://flashrom.org/release_notes/devel.html#known-issues
I do not believe that I have a larger than 16MB BIOS flash.
Below is the output from lshw which shows 8MB BIOS.
I did see that the AMD GX-412TC SOC does integrate the Fusion Controller Hub.
I did run the flashrom command with the -vv and -vvv options, output where the
failure is below.
If anything is relevant to fixing the issue let me know.
Otherwise, I am willing to close this issue unless you have a reason to keep it
open.
These computers are end of life and I will use them for as long as they last.
My goal was to just get them to the last BIOS update I could find.
Thank you again for your assistance,
Victor
