BIOS archive of about 3.6 MB for the HP 14-b050tu laptop on Quanta board DA0U33MB6D0, revision D, project U33. Quanta builds many HP consumer notebooks and encodes the project in the DA0XXXMB number printed on the PCB. The image is used to reflash the SPI BIOS chip with a programmer like CH341A when the laptop is dead after a failed update or shows no display. Confirm both board number and revision on your PCB, read and keep the original chip contents, and check the image size against the chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
