Change Boot Partition

[mbrossar]

Is there a way to change the boot partition on a nano pfSense installation if the server won't boot in the first place?  I just updated my m1n1 to v 2.3.3, and it bricked.  I did copy the boot slice before the upgrade, but I don't know if I can get to the other slice if the box won't boot at all.  Am I looking at a rebuild?

Early as it starts, the console will give you a prompt to press 1 or 2 to select/switch the boot slice (I think it says F1 or F2, but you actually press the normal ASCII 1 or 2 number key)
