After purchasing a A7N8X-E and trying to run a Knoppix based distribution on this machine, I have discovered that the NForce2 chipsets (MoBo, LAN...) doesn't run well on Linux. I googled and found this:

Linux nForce2 nvnet driver Petition

I want to request for everyone to sign this petition. If this doesn't works, well, I'll have to buy a KT600 based MoBo...
