RAR archive for the Lenovo IdeaPad 5-14ITL05, machine type 82FE. The name does not say what is inside, so it may hold BIOS files, drivers or other service material; check the contents before use. The ITL suffix in Lenovo model names refers to Intel Tiger Lake platforms. If the archive contains a firmware image, it should be written to the SPI chip with a programmer only after backing up the original. Before relying on any board-specific data, compare the motherboard number printed on the PCB with what the files describe.
