Compressed BIOS firmware for the ECS H87H3-MV desktop motherboard, version 1.0 hardware, delivered as a small 366 KB RAR archive. The H87 in the model indicates the Intel H87 chipset board family by ECS. Such a file is used to recover a board after a failed update or corrupted flash by writing the image directly to the SPI chip with a programmer. Check that the board version silkscreen reads 1.0, dump the current chip before overwriting it, and confirm the extracted image matches the chip capacity.
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.
