A 4 MB BIOS binary for a Foxconn H61MXP motherboard, marked OK in the name to indicate a working dump, indexed under ECS. The H61 chipset board stores its firmware on an SPI flash chip, and this image can be written with a programmer such as the CH341A to recover a corrupted or dead BIOS. The file size must match the chip capacity, here 32 Mbit, or it will not fit. Read and keep a backup of the existing chip first, and confirm the exact board model and revision before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptop_bios_schematic. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
