Hi,

Brendan - I think you are on the right track. For example, the MESI cache protocol would seem to cover my question. However, all Intel docs I have read refer to coherency in a multi-processor environment. If they were a little more vague and talked about coherency with another agent and not specifically with another CPU, I'd be covered.
I'm thinking this might be covered in books published by Intel Press and not otherwise available on their web site?
The information might be in something published by Intel Press, but (given that this information is only normally needed by chipset designers and Intel engineers) it might be information that Intel only let licensed partners have.
Is there some reason that you need to know more than "yes, it works"?
If it didn't work, then it'd break compatability with every other "PC compatible" computer and seriously annoy developers for all operating systems; and I'd guess Intel are the only ones who can provide something like a written guarantee (which they generally don't do, especially for "medical, life saving, or life sustaining applications") .
Cheers,
Brendan
