Tested BIOS dump for the Lenovo ThinkPad L510, built on a Quanta motherboard numbered DAGC3AMB8H0 at revision H, supplied as a ZIP holding a BIN image. The name marks the image as tested and working. Quanta boards use the DA...MB...0 numbering pattern, so the code silkscreened on the PCB is easy to verify. Write the BIN to the SPI flash with a hardware programmer after backing up the existing contents, and check that the image size equals the chip capacity, otherwise it will not fit or will boot incorrectly.
