   Hi Eric,   
      
   Have you disabled the "Copy Protection" code?  I described it someplace,   
   something about synchronized tracks.  I also supplied Track/Sector locations   
   to disable it by changing one or two bytes in the compiled code.  Since you   
   are compiling SYSTEM.STARTUP    
   (STARTUP.TEXT), you can disable it by changing the code in the CKCOPY   
   procedure.  You might be able to just comment out the call to CKCOPY, but I'm   
   not sure if there are residual effects that are needed by CKCOPY.   
      
   To disable the Copy Protection code in CKCOPY (after it has tried checking the   
   diskette) you can comment out the "IF" line, and just leave the EXIT( CHKCOPY).

   Kind Regards,
