Compatibility: 4.0+
Purpose: Loads and executes a TSR  (before starting AUTOEXEC.BAT).

Uses:   Avoid some memory loss due to DOS environment duplication.

  Hide installation of system-level programs such as Share and
Nlsfunc in the "permanent" CONFIG.SYS file, rather than loading
them in the often-edited AUTOEXEC.BAT file.

  Give your favorite TSR a chance at intercepting interrupt
vectors before COMMAND.COM is loaded.

Syntax: INSTALL=[d:][path]filename.ext [progParms]

  Parameters  

d:\path\filename.ext is the drive, path, filename and extension of the
program to be installed.  Only certain DOS external commands and
third-party TSR  programs can be installed this way.

progParms specifies command-line parameters (filenames, switches, etc.) for
the program being installed.

  TECH Notes  

  On DOS versions prior to DOS 6.0, a TSR loaded via INSTALL= does not
have access to a valid DOS Environment block.  DOS 6.0+ does provide a
copy of the DOS environment and does follow the standards described in

HOWEVER, the environment block does NOT remain in memory after
installation.  TSRs should access it only when starting up.

  Your TSR may wish to allocate upper memory when it is available (see
Accessing Upper Memory for info).  However, you should always provide a
command-line switch to force it to use only conventional  memory (or
you'll irritate folks who are saving their UMBs for special purposes.
