BIOS firmware for the HP 15-n055st notebook on board DA0U92MB6D0 revision D, packed as a 2.31 MB RAR. The DA0xxxMBxx0 pattern is Quanta numbering, so Quanta manufactured this board for HP. A dump like this is used to recover a board with corrupted firmware by writing the SPI chip with a programmer. Check the revision D marking on the PCB, extract with WinRAR or 7-Zip, verify that the image size matches the chip, and keep a backup of the original contents.
