Lenovo firmware for the M3A780M motherboard, version 1.0, in the 2M variant, which most likely means a 2MB flash image; a separate 1M variant also exists. Packed as RAR. Choose the file that matches the capacity of the chip fitted on your board, as an image of the wrong size will not fit. Read and save the original chip with a programmer first, then write and verify. The name gives no further hardware details.
