BIOS dump for the LG R490 notebook, taken from a Quanta-designed mainboard numbered DA0QL2MB8F0, packed in a RAR archive of about 1.13 MB. The file name marks the image as tested and working. The DA0 prefix followed by a project code is typical of Quanta board numbering, so the same PCB may appear in other brands too. Extract the .BIN, read and save the original SPI chip contents with a programmer such as CH341A or RT809H, and confirm the board number on the PCB before writing this image.
