Yes, seriously. The next version won't have all that DMI and ACPI stuff. And if 
there will ever be a version with that again, it will not be labeled "IOT2000" 
via the board name entry. And it will have more robust hardware discovery as 
well. Lesson(s) learned, in fact not only for this product series.
