heeey

i am very happy that i have coreboot running now on my desktop machine...

ADDON-GPU card works now

Nvramcui works

Optionrom execution works.

IOMMU does not work .. debian has to boot with iommu=off.

but KVM virtualsation works somehow.

Suspend does not work.

USB is still extremely buggy ... only the USB3 Ports are useable.
