Working BIOS image for an HP 15 laptop built on the DAG7BLMB8D0 motherboard, with the code 086AA also noted in the name, in a 7.6 MB RAR. DA-prefixed numbers follow Quanta's scheme, and the final characters normally indicate the PCB revision. The dump is intended for writing to the SPI flash with an external programmer when the laptop has no display or is stuck after a failed update. Save the original chip contents first, confirm the board number on the PCB, and check the image size against the chip capacity.
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.
