BIOS firmware archive for the Acer Aspire ES1-520, configuration 54E9. The name does not give the board number, flash chip or ME status, so open the RAR and check the image size and contents before use. Such dumps serve to recover a laptop with corrupted firmware by writing the image directly to the SPI flash with an external programmer. Acer ES1 boards come from different ODMs, so check the board number printed on the PCB against a reliable source. Always back up the existing chip before erasing it.

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 →
