Firmware package for the Lenovo ThinkPad T470s, machine type 20JT, taken from a unit fitted with an Intel Core i5-6300U processor. The ZIP archive is 8.44 MB and is meant for restoring the BIOS on a board that fails to start or is stuck on a corrupted image. Before programming, dump the existing flash with a tool such as a CH341A and keep that copy, because it holds the serial number and other unit-specific data. Also check that each image matches the capacity of the chip you are writing to.
