Lenovo Z50 main BIOS dump of 8 MB, the name noting it has been cut, meaning the region was extracted or trimmed to fit a single flash chip. No board number or revision is given, so verify the motherboard code printed on the PCB before use. The file is meant for writing to the SPI chip with an external programmer after reading and keeping the original. Since the image is 8 MB, the target flash must be 64 Mbit; a different chip size means the wrong image or a different board layout.
