ROM image for the ASUS A45A, linked in the name to the K45A model; no board number or revision is given. The 8 MB file is a full SPI flash dump meant for writing with a hardware programmer such as CH341A. Because the motherboard version is unspecified, inspect the PCB for its board code and compare it with known references before flashing. Always read and store the original chip contents first, then verify the write to ensure the laptop receives a complete image.
