Small firmware archive labelled only QT6B, a Quanta-style project code with no laptop model or full board number in the name. At 100 KB it is far too small for a full BIOS and most likely holds an EC/KBC firmware image. Open the contents and compare them with the board markings, which on Quanta designs read DA0QT6MB followed by a revision. Before flashing an embedded controller, read and keep its existing firmware and confirm the target chip, because a mismatched EC image can leave the board dead.

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 →
