BIOS firmware for the Acer Aspire 1 A114-31 series laptop, compressed into a 3.56 MB RAR. The name gives no board number, revision or version, so check the extracted files and the PCB markings before use. A dump like this is used to rewrite the SPI flash with a hardware programmer when the machine fails to start after a bad update. Always save a copy of the original chip, which can hold serial and key data, and confirm the image length matches the flash 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 →
