BIOS image for Lenovo LCFC board NM-A273, raw BIN of 8.00 MB with no laptop model or revision given in the name. The NM-xxxx pattern is the LCFC numbering used for Lenovo notebooks. An 8 MB dump fits a 64 Mbit SPI flash chip. Use it for recovering corrupted firmware via an external programmer, after confirming the NM-A273 label on the PCB. Save the original chip contents before writing, as they may include machine-specific data such as serial numbers.
