Command: ; (semicolon)

  ';' marks the config.sys line as a comment. ';' has the same effect
  as 'REM' in AUTOEXEC.BAT / FDAUTO.BAT
  ';' is a CONFIG.SYS / FDCONFIG.SYS command.

Syntax:

  ; [comment] OR:
  REM [comment]

Options:

  comment  any comment you want to add to remember why you did this or
           that; can also be a command, which shall not be executed
           (maybe for test purposes).

Comments:

  ';' and 'REM' provide the ability to place comments within the
  configuration file. The text following the ';' or 'REM' until the end
  of the line is reached is ignored. This may also be used to temporarily
  disable loading a particular device or other option.
  ; and REM work both in CONFIG.SYS / FDCONFIG.SYS whereas in
  AUTOEXEC.BAT / FDAUTO.BAT only REM works.
  ';' is a command internal to kernel.sys and needs no other file
  in order to work.

Examples:

  IN CONFIG.SYS / FDCONFIG.SYS:
    REM DOS=HIGH,UMB  WORKS, has the same effect!
    ;DOS=HIGH,UMB     WORKS, has the same effect!

  IN A BATCH FILE / AUTOEXEC.BAT:
    REM DOS=HIGH,UMB  WORKS!
    ;                 DOES NOT WORK !!!
