BIOS archive for the Lenovo CIH61IV desktop board, an Intel H61 chipset design going by the name, packed as a 3.29 MB ZIP. No version or revision is given, and this copy is slightly larger than other CIH61I files, so compare their contents. Images like this are written to the motherboard SPI flash with a programmer to revive a board that no longer boots. Save a full read of the original chip first, since it holds board-specific data, and make sure the dump size matches the chip.
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.
