You are in luck. I've actually got booting code for my ASUS P2b. Both
My main question is: The W83977TF has support under v1, but not v2 - any tips on porting from one to the other?
I've done this already. I'll push the code up in a few hours or so. Its on a machine I don't have local access to right now.
I just committed my framework for the Asus P2B. Hopefully it works for you. It should come up and try to dump the contents of the SPD on the RAM. But like I said its broken even without the Asus magic. I'm going to try and work on that today and see if I can discover something.
So step one for P2B is to work with the board booted under factory BIOS and see if we can figure out what GPIO is used to enable the memory SMbus.
2.6 kernels know how to dump the SPD for a i440bx so see if you can do that. If that works then we just need to start comparing a northbridge dump of the Asus vs a non-asus 440bx and see if any of the GPIO are different.
