I didn't see anything on the Free Software Foundation site on Minnowboard.

http://www.minnowboard.org/meet-minnowboard-max/

Does anyone know more about how free this is?

Also see that uefi firmware can apparently be developed. I don't understand this kind of thing, the firmware isn't free is it?

I wonder if it will suffer from the same problems as the Raspberry Pi.

"We used open source software as much as possible."

Non-free software coming from intel? Shocker.

This seems to be another of those times where you get exited looking into the promise of something but maddeningly there is some non-freedeom included with no easy way to skirt it. Nice to have the no NDAs for mods and it's nice to be able to use free software for the graphics card on these, but I agree that we may be hosed anyway.

Here's something I found from one of the devs though (ray of hope?):

"One way we could resolve this problem is to have a Compatibility Support
Module (CSM) for UEFI that supports legacy boot mode. It may be
possible that this could be implemented with (free) software
(SeaBIOS (LGPLv3)), and I have someone investigating that, but I don't have an
ETA for when that will be released, nor can I promise this is going to
work for all OSes. I'll try to keep folks posted on this as I hear more
information."

CSM doesn't do the hard and machine-specific work that's needed here.

http://uefidk.intel.com/content/minnowboard-uefi-firmware-eula states
that "The CPU and chipset initialization code is currently provided as a
binary module" which is consistent with usual Intel support for coreboot
(MRC, FSP) and makes it useless without hard reverse engineering work.
I don't know if it has signed blobs like most Intel devices have.

Realizing that I do not understand this stuff, which is why I posted the question above, I note that Intel's video says uefi secure boot can be disabled http://youtu.be/eAnlhkbMang?t=20s

I'm not sure that makes any difference to your discussion but I wanted to mention it.
