BIOS image for the Acer Aspire 5520G laptop, saved as a 1.00 MB ROM file. The name gives no board number, revision or firmware version, so confirm the motherboard identity before use. A 1 MB image corresponds to an 8 Mbit SPI flash chip, which is typical for laptops of this generation. Technicians write such dumps with a programmer like the CH341A to revive a board with corrupted firmware. Read and save the original chip contents first, and verify that the chip capacity matches the image size before writing anything.
