Fortune was on my side when I extracted the same spi flash chip from my
junk collection that this mini itx uses. A freshly downloaded bios image
was flashed with external ft2232h to recycled flash and swapped with
original chip. I followed the suggested methodology to test unknown
hardware, output of hardware probing was piped to attached text files.
Read, write, erase and probe work as intended. Diff returned no file
differences and pc booted as expected using A07, A08 and backup binary
