Understanding Linker Map File (MS Visual Studio 2005)

Question

All -

I'm trying to understand the first section of the Map file produced by the MS Visual Studio 2005 linker. I know it has something to do with memory sections, but can someone help me decipher it?

Answer 1

Here is a good reference. I've been looking for this myself, as MSDN apparently provides no information whatsoever about them.

Answer 2

Those are just the object sections that need to be merged into image sections. Read up on PE and COFF if you're not sure what that means.
