   I'm amazed at how much you managed to fit in one sector. There are some   
   learning points - for example, I hadn't thought of using pusha and popa   
   - but more importantly it looks as though you load entire clusters at   
   once. I hadn't thought of that and had been doing it sector by sector.   
      
   What did you mean about the overflow bug?
