Something I just realized. When am using filo I can use the keyboard input but this is in fact coming from the UART link, not the PS2 connector itself, sorry for that.
However, I've tried to press F12, on the UART client as well as on the PS2 keyboard, I cannot reach seabios menu.
Okay, that is different - it leads me to believe that coreboot isn't turning on your ps2 port.
SeaBIOS does not read keys from the serial port. If you wish to do that then add the sgabios optionrom to the flash - see the directions at:
http://www.coreboot.org/SeaBIOS
Something is indeed very wrong as using coreboot as BIOS does not initialize the keyboard in fact. Pressing "num lock" on the keyboard does not change the LED status. With the legacy BIOS it does of course.
It's SeaBIOS that implements the numlock led - since SeaBIOS can't access the ps2 port it wont work.
I am sending you what you have asked anyway. So I guess as for the VGA we are back to coreboot code base?
I think we need to get input from the coreboot experts.

The mtarvon mainboard config in coreboot only sets up the SuperIO-like device embedded in the CPU for the internal UARTs; it does not set up an external SuperIO at all.
I never bothered with the external SuperIO as I had no need for it. If you want to use it, you'll have to modify Config.lb appropriately; see the jarrell mainboard Config.lb for an example.

Hello Ed and others,
Nice for the update. I will proceed with enabling this and provide you guys with a patch. I will be working on another project for the next two weeks so do not expect it tomorrow.
The last remaining items would be the VGA output. Do you see any problems in your port that would prevent to use an external GFX card? I've been able to use the DMA engine part of our PMC cards so I believe the PCIe itself is trained correctly.
We are using a PMC<->PCIe adapter and these cards operate 100%. That makes the VGA issues even weirder, doesn't it?
Have you tried to use the G550 GFX shipped along with the Truxton dev kit? Did it work?
Thank you!
Arnaud

I was able to use a PCIe Ethernet card so PCIe itself isn't likely the problem. I didn't even try to get VGA to work, though.
