BIOS firmware archive for an HP laptop built on the Quanta motherboard DA0X21MB6D0, revision D. The DA0...MB6D0 pattern is Quanta's numbering, so the board number silkscreened on the PCB is the reliable reference rather than the HP model name. Inside the RAR you should expect a dump intended for the SPI flash chip, written with a programmer such as a CH341A or RT809. Confirm the board number and revision match, save the original chip contents first, and check the image size equals the chip capacity before writing.

How to open a .rar file
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 →
