BIOS dump for the HSN-Q26C laptop motherboard DA0XW5MBAD0, revision D. HSN-Q codes are HP regulatory model numbers, and the DA0 board numbering follows the Quanta pattern, the ODM behind this design. The 20.6 MB RAR archive probably contains more than one image or a full SPI read; check its contents before use. Use it to reprogram the BIOS chip with a programmer on a board that does not start. Confirm the PCB shows DA0XW5MBAD0 rev D, back up the original chip to preserve serial data, and match the image to the chip size.
