Acer Aspire 5520 BIOS image, 1 MB, marked as a read, meaning it was dumped from a physical flash chip rather than extracted from a vendor update package. A dump taken from a real board normally carries configuration data along with the firmware itself. It is meant for reprogramming a 1 MB SPI chip with a hardware programmer when the laptop powers on but shows no image or fails to boot. Save the original chip first and confirm the model, as the 5520G may need a different image.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
