[MinnowBoard] BIOS/UEFI/Firmware settings hotkey?

All,
I don't think this solves Jack's issue, as he does not want to boot into
the UiApp every boot, but instead he is looking for a way to enter the app
on select boots without first booting to the shell then exiting to the boot
menu.
This is why I suggest trying to spam the '+' or '-' key to see if it brings
up the boot menu before booting to the shell.
