BIOS archive for the ASUS X555BA with an AMD A9 processor, running on the X555BQ mainboard, revision 2.0. ASUS names its boards after the model, and one board often serves several retail models, which is why a X555BA uses the X555BQ board. The dump is intended for reflashing the SPI BIOS chip with a hardware programmer. Check that the board name and rev 2.0 printed on the PCB match, read and store the original chip first, and confirm the image size equals the chip capacity.
