Raw 8 MB BIOS image for a Lenovo laptop on LCFC board NM-A311 revision 1.0, with codes ACLU9 and ACLU0 in the name. Those are LCFC project identifiers rather than a retail model name. NM-A numbers are used by LCFC, the Lenovo-owned ODM. The 8 MB size suits a 64 Mbit SPI flash chip such as a 25-series SOIC8 part. Read and back up the original chip first, confirm the board label and revision, and only then write this image with a programmer.
