BIOS and EC firmware for an HP laptop with the Quanta GHD motherboard, DAGHDMB8D0 revision D, packed as a 7.24 MB RAR with a 16MB BIOS image. Having the EC file helps when a board will not power on or the keyboard and charging misbehave because of a corrupted embedded controller. Quanta part numbers carry the project code before MB, and the revision letter is printed on the PCB. Back up both chips before writing and check each image size matches its flash part.

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 →
