I have checked that, and have deleted amdgpu from my system. There are no amdgpu anymore. The more i think about this, I had originally converted 18-20 LTS to run on my 1,1 for the 32bit efi to run with the 64bit processors. I was running legacy drivers I believe. Upgrading just did not fool with it until 21. I had just swapped HD's from 1,1 to 3,1 so i had the 64efi and 64cpu. Something in that process made this a whole lot easier for I have never even heard of this problem with SSE4,2 being that both processors are from the same family. Also, as of the processors, I can not swap a newer processor that handles SSE4.2 onto this motherboard unfortunately!!! I can just emulate at this point, or get a Pro4,1 dual processor for $200. No graphics card needed. I still have my 1,1 just sitting over here...... I will poke along with what I can find, do not have the extra $200 right now. Thanks
