BIOS dump from a Lenovo G50-45, saved as an 8.00 MB binary and marked OK, indicating a working image from a functioning machine. The size fits a 64 Mbit SPI chip, written with an external programmer to restore boards that will not post or show a display. The name gives no board number, so check the mainboard silkscreen before using it. Keep a backup of your original contents since they carry unique serial and identification data, and confirm the write with a verify pass.
