Well, I sort of figured it out. I can go through the firmware update process. At least, I *think* it's updating. After that, it seems to be operating normally. But whenever I power it up, it goes into firmware-update mode. I can't get it out of that mode unless I go through the update process. Yes, I've tried to remove and restore the power. I really don't want to have to install firmware every time up power up the rig!
