Brandon, Also that PCD is defined as "FixedAtBuild" so you cannot change it at boot time by PcdSet. Those PCDs with "Dynamic" attribute support boot time value change by PcdSet.

It declares the existence of, and a generic default value for, a PCD entry. This is like a system header. The .DSC file is the project build file and it is the file you should be modifying. The idea is a vendor can send you a package with .DEC files and drivers (.INF) files. You can build a project in a different package that pulls in various other packages and this is done via your custom .DSC file. You can override default values in the 3rd party package in your .DSC file and not need to make any changes in the vendors package.
