BIOS dump for the HP 15-n055st notebook on the Quanta DA0U92MB6D0 motherboard, revision D, in a 2.31 MB RAR archive. Quanta uses the DA0xxxMBxx0 numbering, with the project code embedded, so compare the full number and revision on the PCB before flashing. Such dumps serve to restore boards with a corrupted SPI image showing no display or no boot. Extract the file, dump and keep the original chip content with a programmer, and verify the image matches the flash 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.
