The FAE told me that he does not want to join the mailing list, so I will exchange the information from/to Kontron off-band and push them to the list if I get updates.

Above it (0000:01:00.0) is the external NIC which comes up with 'anything' (but 'anything' is the same after each power cycle)!? > Some explanations to the HW setup, the BYT resides on a Kontron nanoETX board, the external controller is on the custom base board, it is not at all integrated into the BIOS setup (the BIOS should only take care of the internal NIC). > The datasheet states that the page selection register should come up with 0 after power on, but either somebody writes the register up-front (but who) or this comes from a broken setup in the NVM? > > Jochen > -- > Henneberg - Systemdesign > Jochen Henneberg > Loehnfeld 26 > 21423 Winsen (Luhe) > -- > Fon: +49 4174 668 773 > Mobile: +49 172 160 14 69 > Fax: +49 321 210 761 64 > www: www.henneberg-systemdesign.com > > > -- Henneberg - Systemdesign Jochen Henneberg Loehnfeld 26 21423 Winsen (Luhe) -- Fon: +49 4174 668 773 Mobile: +49 172 160 14 69 Fax: +49 321 210 761 64 www: www.henneberg-systemdesign.com
