However, without an internet connection its a bit tricky to get them into the system. Here is the approach I believe will work, but wanted to check first before I really mess things up.

No idea what the default partitioning is for BSDInstall. However the Mini is only EFI or UFEI with some fallbacks although the comments I find in the web indicate that different models have different fallbacks.
One comment indicates that an older unit will boot if its MBR partitioning. I don't know if the new installer supports that or not.

I wrote a FreeBSD BootEasy boot into the MBR of the Windows disk and it CAN boot the GPT disk just fine. Not ideal for most, but it works well for me
Based on a comment I say, waiting till the empty folder icon appears and then plugging in the install memstick causes the mini to boot from disk. That just downright weird, but it works. I could live with that, but this is an unattended server and would experience some down time if I am not there when there is a power failure.
I just found some "instructions" for using MBR with bsdinstall, but given there is an effort to create a UEFI boot which I suspect would expect to find the GPT boot partition, perhaps I should just go with the memstick approach?
