BIOS image for the Dell Chromebook 11 3120 on the Quanta ZM8 board, DA0ZM8MB6D0, revision D, described as a Windows BIOS, meaning firmware replacing the stock ChromeOS firmware to allow a standard OS. The small 1.36 MB RAR suits SPI programming with an external tool. Chromebooks often use write protection, so check that before flashing. Confirm the Quanta board number and revision on the PCB, and keep a backup of the original firmware to return to ChromeOS if needed.
