   CP/AM seems to follow the same approach.  I'm going to assume that all 140KB   
   disks wrap around, and use the directory contents to determine whether or not   
   the first 3 tracks are available.   
      
   The CiderPress II disk formatter takes a "make bootable" flag.  For CP/M I   
   think that'll mean whether or not to add the magic extent at the start of the   
   directory.  I'm undecided on whether to output an OS image to make the disk   
   actually bootable, the    
   way I do for DOS 3.3, because every version of the OS is just a little   
   different.  Chapter 3 in the CP/AM manual explains how to put your choice of   
   OS on a floppy disk or other device (four different installers, "COPY /S" from   
   an existing disk, etc.), so    
   I don't think leaving the boot tracks blank will slow anybody down.   
      
   Seen in the boot block: "Update to Ver R5.1.1S by Steven Hirsch in 1986" ...   
   anybody we know? :-)
