Firmware archive for the Acer Extensa 4120 notebook, a compact 564 KB RAR with no board number given in the name. Because the motherboard code is not stated, identify the board printed on your PCB and confirm the image suits it before writing. Older Acer laptops of this kind often use small flash chips, so check that the extracted image size fits the part on your board. Technicians use such dumps to revive boards with corrupted BIOS through an external programmer, always saving the original chip contents beforehand.
