Hi Patrick!
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
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.
How to check if it's compressed?
Best regards,
n3ph
