BIOS and EC firmware package for a Lenovo system built on the LCFC board NM-A272 revision 1.0, with ACLU1 and ACLU2 codes that identify the platform, in its UMA variant using integrated graphics only. The 7z archive holds the system BIOS together with the embedded controller firmware. NM-prefixed numbers follow the LCFC numbering used on Lenovo boards. Confirm the PCB number and revision, and that the board has no discrete GPU, then back up the original SPI chip with a programmer before writing either image.
