Lenovo G50-80 BIOS dump for the NM-A632 motherboard, an 8 MB BIN image. NM-prefixed numbers follow the LCFC numbering used for Lenovo-designed boards. The 8 MB size suits a 64 Mbit SPI chip and will normally contain the full flash including ME and BIOS. Use it to recover a G50-80 with corrupted firmware via an external programmer. Confirm NM-A632 on the PCB, since the G50 series used several boards, and read the original chip first to keep its serial and Windows key data.
