Firmware dump for the Toshiba Satellite Pro L830, built on the Quanta mainboard DA0BU8MB8D0, revision D. Quanta numbers follow the DA0 + project code + MB pattern, and the trailing letters mark the PCB revision, so check the silkscreen on your board matches. The 2.58 MB RAR archive should contain an SPI BIOS image for reflashing with an external programmer after a failed update or corruption. Back up the existing chip before writing, and make sure the image size equals the flash capacity.
