I've gone through the instructions in the past few months and finally made time today to update the firmware - step by step, got to the "Verify Serial Port" screen, clicked on "Select Serial Port" drop down box and was presented with ONE choice: "Intel(R) Active Ma...ology-SOL(COM3)". Since that was the only choice, I selected it, and then this message appeared: "Couldn't verify Serial Connection on Intel(R) Active Management Technology". Total gibberish. I've never had trouble selecting or connecting to a COM port, but this is baffling, so I had to unplug and give up on updating my firmware. What now?
