How to upgrade firmware?

Visit the DVD-ROM drive's manufacturer's official website to see if there is any new firmware available for your model. And be sure to match the model number, as the firmware for different models are NOT interchangeable. When confirmed,  please download the firmware file to a location you can find later. Go to the location where you just stored the file for upgrade. Execute the file and wait for the program to confirm the operations. Always remember to reboot your system after completion. After the system re-boots, double check the firmware version in the "Device Manager".
