Working BIOS for the HP OMEN 15-en0031 gaming laptop on Quanta motherboard DAG3EDMB8D0 revision D, reported as fully working. The 7.99 MB RAR should hold the SPI flash image for recovering a board with corrupted firmware. DA-prefixed codes follow Quanta's numbering, and HP uses Quanta for many OMEN models. Match the board code and revision on the PCB, read and keep the original chip contents with a programmer, and verify the image size matches the flash chip.
