OK, Thanks. Thats the information I needed.

Thank you, now I understand. So that means if I want to use Marlin 2 I have to change the mother board to a Ver 4 so that it will update?

OK, what does "Hi, you need to correspond to your motherboard model." mean? I'm not a computer geek. I need an answer I can understand. Thanks for the reply.

My A20M into screen says I have GT2560 3.1 Do I need to up date that to 4.0? If so how do I do that?
