Firmware archive for the AMD-based Lenovo G405, 1.84 MB in ZIP form. No board number or BIOS version appears in the name, so identify the mainboard code printed on your PCB before relying on the contents. Dumps like this are written to the SPI flash with an external programmer when a laptop fails to post or was bricked by a bad update. Keep an untouched read of the original chip as a fallback, and confirm the image size matches the chip capacity, otherwise it will not fit.
