On the Firmware tab all of the buttons were disabled because the "USB" button didn't have a drop-down list to choose a port. After some fiddling, I found that if I disconnected the usb cable and reconnected it, for a few seconds I could choose the COM port. Once I did that, the buttons became enabled allowing me to choose the "Safe Boot" button. Once the quad rebooted into safe mode, I was able to disable the incorrect setting on the "Hardware" tab.
Thank you for being my safety net in case I really screwed things up.
