As I mentioned a few weeks ago, I am in the process of porting this board:
http://www.technexion.com/products/embedded_boards/tim-8690-mt.html
This board has a dual BIOS , choosable with a jumper - much like the BIOS
savier from before - so it is a pleasure to work with as a linuxbios developer.
It is still a work in progress, however , I already submit the patch.
All on board devices and slots work as expected, only need some more stress
testing with the RAM, acpi, etc..
