BIOS dump for an Acer system with board marking B36H4-AI, described as fully working, in a 9.44 MB RAR archive. The name gives no laptop model, chip size or version, so the board marking is the key match point. A dump like this is used to recover a board with corrupted firmware by writing it directly to the SPI chip with a programmer. Confirm that the PCB carries the same B36H4-AI label, back up the existing contents, and check that the image size matches 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 →
