BIOS firmware package for an HP Pavilion 15 built on the Quanta motherboard DAX1BMB1AF0, packed as a 5.04 MB zip archive. The DAX prefix with MB marks Quanta numbering, so HP is the brand while Quanta designed the board. Technicians use a dump like this to reflash the SPI chip with a programmer such as a CH341A when the laptop will not boot or shows a black screen. Confirm the board number silkscreened on the PCB matches, read and save the original chip contents first, and check that the image size equals the flash 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 @bios_laptop. Enginerys does not host this file.
