BIOS dump for the Lenovo G50-80 laptop with board number NM-A361, a code from the LCFC numbering scheme used by Lenovo's Hefei ODM factory. The 8 MB file matches a 64 Mbit SPI flash chip and is written with an external programmer. Technicians use it to recover a board that does not start after corrupted firmware or a failed update. Check that NM-A361 is printed on the PCB, as G50 models used several boards, and back up the original chip, which holds serial data.
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.
