   Yes I realized that, but I want to manually create an UEFI conform GPT   
   start up sector with only four entries (FAT32 as the first).

   well known BS, my OS never wasted any sector. my now old KESYS used code   
   in the MBR as first part of the OS core and it continued on LBA_1.   
   so the whole OS-image (512MB) is stored in consecutive order on disk.   
      
   I'll keep this for the new 64bit version even the start may not be on   
   LBA_0 due to the UEFI/GPT stuff.
