BOOTDMOD.ZIP    Modifies disk BOOT record and cluster size

Brief information from documentation:

   Summary:
   =======
   Allows modification of following disk(ette) parameters:
          - sectors per cluster
          - number of root directory entries

   Purpose
   =======
   BOOTDMOD is meant to optimize disk space for special situations.

   Examples
   ========
   FORMAT does not allow a free choice of clustersize and number of
   root-directory entries, while there are situations where other than
   the default value is desirable, for example:
     - A large number of relatively small files might cause waste of
       a considerable amount of disk space. An example of this is a
       bulletin board program OPUS: every message is a DOS file, of
       which there may be thousands present. If average messagesize is
       1 KB, while the clustersize will generally be 2 KB (4 sectors of
       512 bytes), then half of the diskspace will be unused.
       With BOOTDMOD a 1 KB cluster (2 sectors) can be created, or even
       a 1 sector cluster, resulting in much better disk utilisation.
     - When a strict directory structure is maintained, and with very few
       root-directory entries, the non-used directory entries might be
       freed for data-storage.
   In these cases BOOTDMOD may be applied after FORMAT to modify a disk
   or diskette to obtain a better utilisation.
