I have put together these installation companion documents for FIM 2010 R2. Basically, I am going through a clean installation of FIM 2010 R2 in a distributed setup against clean Windows Server 2008 R2 systems. I am using Hyper-V for everything except my SQL Server which is a physical box. Here is the collection of the installation companion documents.
The below wiki page is information that was discovered during some FIM 2010 R2 Lab installations here in support.
Here are some of the official TechNet Documentation as well covering installation.
