BIOS firmware for the HP 15-n055st notebook on the DA0U92MB6D0 motherboard at revision D, packed as a 2.31 MB RAR archive. Board numbers starting with DA0 and ending in MB6D0 are Quanta designations, so Quanta manufactured this board for HP. The dump serves to rewrite the SPI BIOS chip with an external programmer when the laptop powers on with no image or after a failed update. Match the board number and revision on the PCB, keep a backup of the original chip, and check the image size.
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.
