Small ZIP archive tied to the Lenovo G50-80 notebook, with the extra token a361 in the name whose meaning is not stated. At only about 40 KB, the archive is far too small to hold a full BIOS image, so it likely contains an EC firmware, a patch or a partial region rather than a complete flash dump. Extract it and inspect the contents before use. Match the file against the chip it is meant for, confirm its size fits, and back up whatever is currently on the chip before flashing with a programmer.
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.
