  3. All we need to do is to toggle the switch number 5 to on position. This will override any password that has been made in BIOS.
  4. If You are also willing to reset NVRAM and CMOS settings, you need to toggle the switch number 6 to on position too. But this is just optional, if this is not necessary you can skip this step.
  5. Turn on your server, and wait until it tries to boot to hard drive. Soon, there will be a long text like this :
    "Maintenance switch detected in the On Position. The system is being default configured. This may take a few minutes..."
  6. You must wait until this text comes up :

  7. Turn off your server and switch off the number 5 toggle (and number 6 too if you do step 4)
  8. Turn on your server. Now you should be able to make changes to BIOS
