I didn't follow this thread (I didn't feel a need), but this info is 
incorrect if DOS was not changed. 

DOS FORMAT command's default cluster sizes are:

 FAT partition  Cluster Size
 -------------  ------------
    0 -   15MB     4KB
   16 -  127MB     2KB
  128 -  255MB     4KB
  256 -  511MB     8KB
  512 - 1023MB    16KB
 1024 - 2047MB    32KB
 ...              ...
 -------------  ------------

 12-bit FAT is used for a partition of less than 16MB, but
 16-bit FAT is used for any bigger parition (>= 16MB).

BTW, I don't support the original poster's request (in the subject).
FAT file system should be replaced rather than the way of djgpp's 
file packaging. (16-bit FAT is too small.) 
Though the best partition size depends on the number of files and 
the total file size, I think 255MB partition size would be the 
best for most users for an FAT system if a big disk needs to be 
partitioned into smaller pieces.  (Since we need to keep some free
work space (maybe at least a few MB) in each partition, having two 
127MB partitions cannot save much comparing with one 255MB partition.)

(I'm happy with OS/2's HPFS (0.5KB/cluster for any partition size).)
