BIOS package for the Lenovo M2610D desktop built on the IH61M board, version 4.2 as stated in the name. The 5.12 MB RAR archive contains images for a 2MB and a 4MB flash chip. IH61M is an H61-based Lenovo OEM board, and its versions often differ in layout and chip arrangement, so confirm the 4.2 marking on the PCB. Read and keep the original contents with an SPI programmer before flashing. Make sure each dump goes to the chip whose capacity it matches.
