The biggest difference between the 7520 and the 3100 is that the 3100
uses DDR2 memory. This requires a more complex initialization sequence.
I suggest the following information:
Especially chapters 10.1.2.2 and 12 might be interesting.
Given the difference to the e75xx is not too fundamental, you might be
lucky with this information, but chances are good that you need the Core
Duo BIOS Writer's Guide, which Intel is giving out under an NDA.
