BIOS dump for the Esonic H81-BTC-KING desktop motherboard, an Intel H81 board aimed at mining rigs, packed as a 2.66 MB RAR. The name indicates the image is meant for a 4 MB flash chip. It is used to reprogram a corrupted or wrongly updated SPI BIOS with an external programmer when the board will not post. Verify the flash part is indeed 4 MB, read and keep a copy of the existing contents, and confirm the exact board model printed on the PCB before writing the file.
