VGA works, after hacking the vgabios to not have the PCI ID hardcoded elsewhere. Nevertheless /me gets the feeling that we better should not take that route. vgabios needs special patching to work. etherboot does not work as-is. Even if we make it work now it always will be fragile. The next rom update might break it again. The ID automagically adapting doesn't happen on real hardware ... cheers, Gerd
