Firmware archive for the Lenovo IdeaPad S340-15IWL, 5.75 MB in RAR form, with no board number, revision or chip details in the name. Before using it, read the motherboard code from the PCB and compare it with what is inside the archive. A technician would normally write this image to the SPI BIOS chip with an external programmer after a failed update or corrupted firmware. Always keep a backup of the original read, and verify that the image length matches the chip size so the write completes cleanly.
