Zipped BIOS binary for the LCFC board AIUU2 NM-A321 revision 1.0, the platform used in the Lenovo Yoga 3 Pro. The 3.70 MB archive holds a raw .bin image for direct programming into the SPI flash with an external programmer. LCFC, Lenovo's manufacturing affiliate, uses the NM- prefix and a project code such as AIUU2. Confirm the board number and revision printed on the PCB, check that the extracted image matches the chip capacity, and back up the original firmware first.
