well look at this we only have 8 chars but we need 12, but if we look at eax
its missing chars so we can just make them up. ie
 
 
 
eax-Pos-00-38-8
eax-Pos-01-
eax-pos-02-33-3
eax-pos-03-31-1
eax-pos-04-39-9
eax-pos-05-
eax-pos-06-
eax-pos-07-
eax-pos-08-30-0
eax-pos-09-35-5
eax-pos-0a-53-S
eax-pos-0b-45-E
