BIOS image for a Lenovo laptop on Quanta board DALVACMB8D0 revision D, with the Management Engine region cleared and the name marking it tested OK. DA-prefixed codes identify Quanta as the ODM. No laptop model is named, so match the board number printed on the PCB rather than the retail model. Extract the RAR, check that the image size fits the flash chip, and save the existing contents with your programmer before writing, so the original serial data can be restored.
