BIOS binary for a Lenovo G50-80 variant, with the name pointing to the Haswell platform and a chip marked 7030, likely the onboard flash or a part reference. The 8.00 MB size matches a 64 Mbit SPI flash chip. No motherboard number is given, and G50-80 boards exist in several versions, so verify the PCB label and CPU generation before use. Flash it with an external programmer, and always back up the existing chip contents beforehand so the original data can be restored if the image misbehaves.
