BIOS image for Lenovo board NM-B241 in a 5.04 MB ZIP; the name does not specify the laptop model. NM- numbers belong to LCFC, the Lenovo-owned ODM that designs many IdeaPad and ThinkPad boards. The dump is written to the SPI flash chip with a programmer to revive a board that will not post or has a damaged BIOS. Check the PCB label carefully, since sibling boards like NM-B242 use different firmware, save the original chip contents first, and confirm the image fits the chip capacity.
