Hello Ville,

thanks for your report!

The problem is the locked ME region as quoted above and the SMM
protection, which is both not trivial to work around, sorry.

I have added the board to our list of (un)supported boards (with an
appropriate note) and will commit that later together with other small
changes.

Ok, thanks!

I had a stupidifying problem with the board - if you disable legacy USB by
accident, there's no way to get back to BIOS, since USB keyboard no longer
works during POST. Duh. I hoped I could upgrade the BIOS from Linux and get
rid of the problem.

Ripping the battery off for a good while helped, and I was able to upgrade
the BIOS at POST.

Anyway, it would be cool to be able to flash BIOS from Linux.

best regards,
