BIOS image for an HP 15 series laptop on Quanta board DA0U92MB6D0, revision D, labelled as fully working. The DA0xxxMBxx0 pattern is Quanta's ODM code, and U92 is the project identifier on this board. A dump like this is written to the SPI flash with a programmer to revive a board stuck with a black screen or a boot loop caused by corrupt firmware. Read and save the original chip before erasing it, check that the file size equals the chip capacity, and confirm revision D on the PCB.
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.
