Very good. I hope this file is still OK.

Doesn't matter. You have no "-v" now, but this still rewrites the
current imae.

This one very much looks like there is a write protection enabled on
your board flashrom doesn't know how to remove, and nothing has changed
yet. If you run
 flashrom -v current_bios_amibios3.19.img
and it outputs "VERIFIED" you know that the data in your flash chip is
unmodified and you are safe to reboot. If a flashrom developer finds
some time, he might try to add support for your board to flashrom.
