Unlocked BIOS image packed in a RAR archive of 1.20 MB, labelled M920 PVT, which points to a production validation test build of the M920 motherboard design; the name gives no laptop model or brand. Unlocked dumps typically have the supervisor or power-on password removed so a locked machine can be used again. Before writing it with an SPI programmer, read and save the original chip contents, confirm the board code printed on the PCB matches M920, and check that the image size equals the flash chip capacity.
