BIOS archive for the Lenovo board NM-A331, revision 1.0, project code AILG1. NM-numbered boards come from LCFC, the ODM that builds many Lenovo notebooks. The 3.59 MB ZIP is used to reflash the SPI flash with an external programmer when the machine fails to post, shows a corrupted BIOS or will not power on correctly. Before writing, read and keep the original dump, which may hold serial and system data, and check the chip capacity against the image.
