Name confusion Alex, os9 has been calling that disk area from LSN1 to 
LSN$100 (max, or however many it takes) the FAT since its first release.  
The address of the / directory in LSN0 is for its FD sector to start in the 
next sector after the FAT, and the directory itself is the next 7 sectors 
in sequence.

Cheers, Gene
