Command: echo (config.sys command)

  BATCH-FILE/AUTOEXEC.BAT/COMMAND.COM version.
  ECHO is a CONFIG.SYS / FDCONFIG.SYS command.
Syntax:
  ECHO [message]
Options:
  message  The message you want to be displayed to the user.
Comments:
  ECHO displays (echos) its arguments to the console during CONFIG.SYS /
  FDCONFIG.SYS processing when device drivers are loaded (when DEVICE=  lines are executed).
  ECHO is a command internal to kernel.sys and needs no other file
  in order to work. There also exists a command.com ECHO command with
  different options.

  IN CONFIG.SYS / FDCONFIG.SYS:
    ECHO loading driver1
    device=Driver1.sys
