@ghill Can you post screenshots of the area you’re working in to set Option 066 ? The immediate issues are probably there.
But yeah I’d say set up an old computer for testing. And as far as testing iterations go, well… you only need one iteration if you’re following one of our more recent tutorials.
Which brings me back to another point. You said you installed fog based on information in several guides on the internet… Are you aware that the fogproject has it’s own wiki? Things you find on other sites are highly likely to be very obsolete and will probably break more stuff and cause more complications when you try them on FOG Trunk with recent Linux versions.
