Lenovo firmware for the IH61M desktop motherboard, version 4.2, marked OK in the name, meaning the uploader reports it as working. The 2.80 MB RAR archive holds the dump, and the name says nothing about the flash chip. IH61M points to an Intel H61 chipset board used in Lenovo desktops. Unpack it and check that the image size matches the SPI chip on your board before flashing with an external programmer. Read and keep the original contents first, and confirm the board marking matches IH61M.
