Hello Ed,

We have received the truxton board a few days ago.

I have compiled coreboot-v2 as well as FILO and created the rom image. 
I've placed the image in
the flash using flashrom, everything there went smoothly.

I tried to launch the system but the system does not boot. Is coreboot 
on truxton supposed to output
something to the G550 PCIe gfx card shipped along with the  truxton 
mainboard or not? The default
AMI bios is able to do that obviously.

The board state after a reboot is

1) No active VGA output
2) The two seven segments displays  on the main board is display 80

I am still waiting my UART dongle so I cannot say if anything goes out 
from the com ports.

Is it a normal behavior Ed or my coreboot image is simply not working?

In advance, thank you for your pointers.

With my best regards,
