I provided bad info and confused you, I apologize. The first update I made and tried with both CPUs was AI, the latest stable and for the 2000 series. When that didn't work I tried AKM and then tried AC, now back to AI. It could still create a problem, I am assuming, but I thought it might be worth mentioning I tried a 2000 series first, before I tried the beta / 3000 series BIOS version.But there was an issue to start with. First flashed AKM, was abysmally slow with the A6, then flashed AC on top, and no joy with any cpu. Broke an 'Armored' pcie slot? So far, the A6 is the only thing that works, none of the non-APU are recognised.
Might need to flash by dos prompt from bootable usb instead of mflash.
I'll try the dos flash instead of the normal M-Flash. Hopefully that will take care of this once and for all.
