External Controller provides you a better and convenience way to switch the BIOS status between “Rescue” and “Normal”
without opening the case of your computer. You have to plug the jumper cable to the connector pin (JP30) on the motherboard.
Be careful of the orientation when you connect, the red wire should correspond to Pin1.
