If you talking about Assembler instruction execution - you looking in the wrong place. If you want to know exactly how Wine works - no one will tell you exactly every single step, because you obviously won't understand most of it. Re-read this part: http://www.winehq.org/docs/winedev-guide/c2722#INITIALIZATION If it still makes no sense to you, then start by asking the right questions (what are you trying to do and what doesn't work).
