BIOS firmware for a Lenovo board labelled CFT3I1, version 1.0, supplied as a 4.20 MB RAR archive. The CFT3I1 code is Lenovo's naming for a desktop motherboard, and the image inside is meant for writing to the SPI flash chip with a hardware programmer such as a CH341A or similar. Before flashing, read and save the original chip contents, since they hold serial and licensing data, and confirm that the dump size matches the chip capacity. Check the board marking on the PCB against CFT3I1 to avoid flashing an incompatible image.
