BIOS firmware archive for the Toshiba Satellite L55-B5267 laptop, built on motherboard DA0BLIMB6F0. The DA0...MB6...0 numbering follows the Quanta pattern, so Quanta is the board maker behind this Toshiba model. The 3.64 MB RAR should hold an SPI flash image intended for writing with an external programmer such as a CH341A or RT809H. Compare the board number silkscreened on the PCB before use, read and save the original chip contents first, and confirm the dump size matches the flash 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 →
