BIOS image for the Foxconn H61MXV motherboard, an H61 chipset desktop board listed here under ECS, packed in a 2.85 MB RAR archive. The name carries the code C12F1P05 and the date 8.25.2014, most likely the firmware build and its date. A dump like this is used to recover a board with a corrupted SPI flash by writing it with an external programmer such as a CH341A. Read and save the original chip contents first, confirm the chip capacity matches the image size, and check the board model on the PCB before flashing.
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 @biosarchive. Enginerys does not host this file.
