BIOS firmware archive for the Lenovo Yoga Pro 7 14IRH8, machine type 82Y7, packed as a 9.72 MB RAR. The name gives no motherboard number, so check the PCB marking; Lenovo boards are often designed by LCFC. The extracted image is meant for writing to the SPI flash with a programmer to repair a corrupt or failed BIOS. Confirm that the image size equals the chip capacity, and dump the original chip first so serial and system data can be recovered if required.
