BIOS dump for the Lenovo G50-70, with the name marked ok several times, suggesting the uploader found it working. No board number or revision is given, so compare the motherboard fitted before flashing. The 8 MB image suits a 64 Mbit SPI flash chip and is written with a programmer such as a CH341A to recover a board that fails to start or loops at power-on. Back up the original chip, since it holds the serial number and Windows licence data that may need to be restored afterwards.
