1. Share installation doe NOT have to be specified in config.sys.
1a. if share.(exe ?) is in the root directory it will automatically be loaded
1b. if share is in the directory pointed to for command.com it MAY (should)
    be automatically loaded (I didn't try this but am told it does ...).
1c. share may be installed in the config.sys as shown above
1d. share MAY (should) be able to be installed in the autoexec.bat or at the
    dos prompt (according to the manual).
2. Share is intended for a network environment where different 'jobs' may use
   the  hard disk, and leave the head in a unexpected place.  Share is kinda
   like a hard disk driver (aka dmdrvr.bin) which tries to parse disk I/O
   to see that no application does a unexpected write or read to the disk.
   (That's ok, it doesn't work with windows, windows will happily crash the
   extended partition anyway...)
