BIOS dump for a laptop mainboard numbered DA0P5HMB8H0, revision H, marked as tested and working. The DA0...MB...0 pattern is the Quanta numbering scheme, so the board maker is Quanta even if the laptop carries another brand. The 5.82 MB archive should contain an image to be written to the SPI flash with a programmer such as a CH341A. Read and save the original chip contents first, confirm the revision letter on the PCB, and verify the image size matches the flash capacity.
