Duplicate firmware dump for the ProBook 450 G1 FIJI mainboard, Wistron-style board number 12238-1, sized 8.00 MB to suit a 64-Mbit flash chip. The name carries no revision, ME status or BIOS version details. A raw image like this is used to reprogram the SPI BIOS chip directly when the laptop powers on without display. Before relying on it, match the PCB silkscreen number, read and keep the existing chip contents, and reapply the serial number and product data afterwards if needed.
