Working BIOS dump for Foxconn H81S and B85S desktop boards, version 1.0, for an 8MB flash chip, labelled as fully working and filed under the ECS brand. A technician uses such a file to revive a board stuck without display or POST after a failed update. Flash it directly to the SPI chip with a programmer and clip. Compare the printed board version first, save the existing chip contents before erasing, and verify that the extracted image matches the 8MB chip capacity exactly before writing.
