BIOS dump for the Acer Aspire 4552, carrying the tokens ZQA and 109, which most likely refer to the platform code and the firmware version. It is a 1.00 MB raw binary sized for an 8 Mbit SPI chip. A dump like this is flashed with an external programmer when the board is bricked by a bad update or a failing chip. Confirm the board code printed on the PCB matches before use, check the flash part capacity, and keep a verified backup of the original contents.
