Hey Paul!
This is actually what i have and as i already wrote in another mail i got the image via:
echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom cp /sys/devices/pci0000:00/0000:00:02.0/rom vgabios.bin

That's your problem. ROM needs to be extracted, not dumped. You can workaround immediate problem by disabling checksum in SeaBIOS but dumped oprom for intel is not fully functional, i.a. LCD stays black with windows.
I guess the rom dumped from linux is broken... I still had no time to try UEFITool - quite busy atm...
Attached .config and bootlog and some cmdline-shizzle...

Dear Michael,

Uhm - I do not explicitly compressed it. I just added it to config..
Extracted it via
echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom cp /sys/devices/pci0000:00/0000:00:02.0/rom vgabios.bin
How to check if it's compressed?
The *file` command should help you.
For my AMD Video BIOS from the ASRock E350M1 I get the following.
$ file vgabios.bin vgabios.rom: BIOS (ia32) ROM Ext. IBM comp. Video (113*512)If the method you used, did not work, please report a bug to the Intel graphics folks [1].
Thanks,
Paul
