Repost to the list, apologies.
Thanks! that will be useful as a template for adding the LGA775 socket.
My CPUs are of the Pentium E5x00 kind, that is Pentium Dual Core based on the Enhanced Core microarchitecture.
The problem is the family is 06 and model 17 (hexadecimals), not directly compatible with the model_xx convention used so far. I don't know how deep is going this convention into coreboot.
Looking at the latest Intel documentation (e.g. 64-ia-32-architectures-software-developer-vol-3b-part-2-manual, october 2011), the CPU microarchitecture main identification is a DisplayFamilyDisplayModel string of the form xx_xxH, x being an hexadecimal digit. I suggest to keep by that convention for the Intel CPUs, something like model_xx_xxH and not model_xx. To make the switch easy, just make model_xx a symlink to model_xx_xxH. Looking for info on a given CPU in Intel doc would be easier.
Comments welcome.
