BIOS image for an HP laptop mainboard DA0Y0MMBAJ0, revision J, marked as working and tested. Board numbers that start with DA0 and end in a revision letter follow the Quanta pattern, so the PCB was made by Quanta for HP. The 4.26 MB RAR archive is meant for reprogramming the SPI flash with a hardware programmer after corruption or a failed update. Confirm that revision J is printed on the board, save a dump of the original chip, and check that the image size matches the flash capacity before writing.</p>

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
