Original BIOS dump for the HP 15-n265st, Quanta board DA0U92MB6D0 revision D, read from a 25Q32FV flash chip and marked as working. The DA0 prefix with MB suffix is typical of Quanta, which builds many HP laptops. The 25Q32 is a 32 Mbit SPI part, so the image should be 4 MB. Use a programmer such as a CH341A to write it when the laptop shows a black screen or fails to post. Read and keep the existing contents first, and confirm the board revision is D.
