A 32 MB BIOS image for the Lenovo ThinkPad X1 Carbon on LCFC board NM-C881. LCFC is Lenovo's own design house, and its boards use the NM-xxxx numbering. Technicians use such dumps to reprogram the SPI flash when an X1 Carbon fails to power up or shows a corrupted BIOS. The name does not give the generation or BIOS version, so confirm the NM code on the PCB and the 32 MB chip capacity. Save the original chip contents, which carry serials and security data.
