Enhanced CONFIG.SYS Options

DOS 6 provides the following enhanced configuration options:

       MultiConfig Menus
       New CONFIG.SYS commands make it possible to display an interactive
       menu of configuration options.  Different sets of commands can be
       executed depending upon the user input.  DOS provides a way to
       specify a timed default selection and a way to continue along a
       particular boot path in the AUTOEXEC.BAT file.
  │F5║ Clean Boot
  ╘══╝ At system startup, you can press F5 (or press and hold SHIFT) to
       bypass the commands in CONFIG.SYS and AUTOEXEC.BAT.  This can get
       you out of a tough situation in which a configuration problem is
       causing a system lockup.  DOS 6.2: Ctrl+F5 also bypasses loading
       of DBLSPACE.BIN.
  │F8║ Interactive Boot
  ╘══╝ If you press F8 during system startup, you will get a chance to
       step through the commands in CONFIG.SYS one-by-one, skipping any
       commands that are causing a problem.  This option also lets you
       bypass execution of AUTOEXEC.BAT.  DOS 6.2: Ctrl+F8 lets you
       process individual commands in AUTOEXEC.BAT.

cmd?=  Place a question mark (e.g., DEVICE?=RAMDRIVE.SYS) in any
       CONFIG.SYS command to be prompted whether to execute that command.

;(rem) Semicolon at the start of a line indicates a remark.

SET    With DOS 6.0+, you can create environment variables in CONFIG.SYS.
