Bricking an UP Board

in UP board BIOS
Did something wrong to my Up Board today. While digging through the bios settings in order to get the board to boot from a USB 16GB finger drive that had a copy of the new Fedora 26 beta install image on it, I encountered a problem. When I reboot, the boot process will not proceed past the AmeriTrends screen. I waited awhile before I noticed that the finger drive was getting awfully hot. I killed power and removed the finger drive. After a few minutes I reconnected power to see if the board would boot from the eMMC as it use to do. No joy. System boot stops at the Ameritrends screen and I cannot edit the bios. I need a few hints about what I should do at this point. The board had been working fine until today.

    I suggest powering up the board with the RTC battery unplugged. That should cause the factory-default BIOS settings to be restored. You can plug the RTC battery in again afterwards.

    Thank you Dan for the reply and the suggestion. Last night I just unplugged the battery and power. I did not power it back up until after about eight hours. This morning I plugged the battery back in, connected power and it booted up just fine. I had kind of figured, belatedly, that this SBC was different from other non-x86 SBC that only needed a battery, if one was present, for the RTC.
