I've tried to use mobile Trinity APU in Llano laptop, but failed with turning on the machine. The pin-layout match, A70M chipset match, wonder if can be other hardver issue or is it only lack of bios support?

More details are here of my test.

Thanks,

Bios or chipset. Trinity puts the northbridge on die IIRC.

Aye, Trinity integrates the Northbridge chipset into the APU itself which grants it several benefits over Llano, but also means no compatibility. But also being a laptop, they most likely wouldn't enable it to work even if it were possible, since they would rather sell you a whole new machine.

That is very interesting. You mean the A70M chipset integrated into the Trinity die, or what is that Northbridge?

All the Northbridge does is serve for an interface between the CPU and RAM (which was eliminated long ago by AMD and a couple of years later by Intel), expansion slots (PCI, PCIe) and connectivity (USB, Firewire, etc) , and the southbridge (which deals with storage connectivity). By moving the Northbridge onto the APU die it helps facilitate giving the GPU direct access to the RAM (no more "shared memory" setting), faster, makes it more compact, and helps it run more efficiently.
