Now that my ME problem is solved I turn to another problem.

The video bios does not seem to function. During seabios boot screen no video is displayed. Only when grub auto loads does the video start.

When I use cbfstool auron_yuna.bin print
it shows pci8086,0406.rom at offset 0x7004c0

However when I check lspci -n it shows an address of 8086:1616 for pci device 00.02.0 VGA compatible controller.

Which of these should I use for coreboot VGA device PCI ID?
