After spending a good 6 more hours googling for answers to my problems with an Abit SG-95 motherboard it seems like I'm going to need to replace it with something a bit more compatible. Other thread:
If you know a good motherboard that works with FC6 out of the box that will go with:
Celeron D CPU (Socket 775)
Please post so I can avoid making such a mistake again...
Please note that those requirements are fairly strict, replacing too many components will be costly.
