RAR archive holding a BIOS for the Lenovo IH61M desktop motherboard, revision 1.0, sized for a 4 MB flash chip. IH61M points to an Intel H61 chipset board used in Lenovo desktop PCs. Use it to recover a board that powers on with no display or is stuck after a failed update. Before writing, check that the revision printed on the PCB matches, confirm the SPI chip is 32 Mbit, and keep a backup read of the original contents in case you need to restore it.
