BIOS dump packed as a ZIP archive for a Quanta-made motherboard numbered DAR18MB6D0, revision D. The DA-prefixed code follows the Quanta numbering pattern, where the letters after DA identify the project and the trailing characters mark the board generation, so the laptop brand itself is not stated in the name. Technicians use such an image to reflash the SPI BIOS chip with a programmer like a CH341A after corruption or a failed update. Confirm the number and revision silkscreened on the PCB match, and save a backup of the original chip before writing.
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.
