Firmware archive for a Lenovo motherboard numbered NM-A751, an LCFC board number, with the name pointing to an 8 MB image intended for a 64 Mbit SPI flash chip. The laptop model itself is not named, so match the NM-A751 code printed on the PCB before use. LCFC is Lenovo's own design arm and uses the NM-xxxx numbering. Technicians typically write such dumps with a CH341A or similar programmer after desoldering or clipping the chip. Save the original contents first, since serials and keys live there.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
