Unsure which one of the 20 stickers on this fkr leads me to the information on the file to flash this mobo with.

let alone any schematic to find where the bios chip is.

any recommendation on software maybe AsProgrammer? Ofc flashrom may work but am uncertain with 1.8v.
It'll work with a Ch341a + 1.8v adapter no?
Should I do Linux instead of Windows??

Thanks much for any consideration.
