BIOS dump for the Lenovo IdeaPad S145-15IWL with LCFC board number NM-C121, compressed into a 5.81 MB ZIP. The name states no version or ME status. LCFC is the Lenovo-Compal venture whose NM- numbers appear on the motherboard silkscreen. The same NM-C121 board is used by other models, so check the board number rather than the model label alone. Write it with an SPI programmer such as a CH341A, after reading and saving the existing chip, and make sure the file size matches the flash capacity before programming.
