BIOS firmware for the ECS H81H3-M4 desktop motherboard, revision V1.0A, compressed into a 3.48 MB RAR archive. The H81 in the model name refers to the Intel H81 chipset this board is built around. Such dumps are written to the SPI flash chip with a hardware programmer like a CH341A when the board fails to POST after a bad update. Read and save the original chip contents first, and confirm the extracted image size matches the chip capacity, otherwise it will not fit.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
