BIOS image for an HP laptop built on the Quanta board DA0Y72MB6C0, revision C, labelled as confirmed working, in a RAR archive of about 4.8 MB. Quanta uses the DA0 prefix, followed by the project code and the MB marking for the mainboard. Such a dump is normally written to the SPI flash chip with a programmer like a CH341A to revive a board with corrupted firmware. Save a copy of the original chip before writing, confirm the revision, and make sure the image size equals the chip capacity.

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 →
