Toshiba BIOS archive for the Quanta-built motherboard DATE1MMB8E0, revision E. Quanta uses the DA-prefixed numbering where the middle letters identify the project and the trailing code marks the board version, so the silkscreen should match exactly. The laptop model is not stated in the name, only the board. A dump like this is written to the SPI flash with an external programmer to fix a corrupted BIOS or a dead board after a failed update. Read and keep the factory image first, and check that the file size fits the installed flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
