BIOS firmware for the LCFC motherboard NM-A331, revision 1.0, with project code AILG1, compressed in a 3.59 MB RAR and filed under Lenovo. LCFC, the Lenovo-owned manufacturer, numbers its boards in the NM-xxxx format seen on the silkscreen. The name carries no model, EC or ME details, so open the archive to inspect the image. Writing it with an SPI programmer can restore a board stuck with corrupt firmware. Read and archive the existing flash before erasing, and confirm the board revision and chip capacity first.
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.
