HP Pavilion 15 BIOS firmware for board DA0X21MB6D0 revision D, in a 2.56 MB ZIP archive. The DA0 prefix is the Quanta numbering pattern, identifying Quanta as the board manufacturer. This kind of image is programmed onto the SPI flash with an external programmer to revive a board with corrupted firmware. Confirm the board number and revision silkscreened on the PCB, read and keep the original chip contents before writing, and verify the file size equals the chip capacity so the image fits.
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.
