Firmware dump for a Toshiba laptop mainboard numbered DABLQMB16B0, revision B, delivered as a 4.09 MB RAR archive. The model name is not stated; the board number follows the Quanta scheme, identifying Quanta as the ODM. Use it to restore a damaged BIOS by writing the SPI flash with a programmer such as a CH341A or RT809. Verify the PCB number and revision before relying on it, back up the existing chip contents, and check that the image size matches the installed chip.
