Great to hear. Glad you can confirm they didn't do too much to change

Can you confirm or reject the theory for adding a switch?

How did you do the socket?

Did you include the VGA BIOS in your LB image and enable VGA in

Does LB find them? Can you show us lspci from factory BIOS and full
serial output from the LB boot?

That could be it. Maybe they changed enough to make the board's
Config.lb invalid.

Carl-Daniel was going to have a look at it when he got back online
unless someone else did it first.

flashrom has no support at all for the SPI way of flashing so I would
just do a massive hack for the first round of SPI support.

Yep - I would expect that to work. Cool.
