Command: fdconfig.sys

  FreeDOS reads the CONFIG.SYS / FDCONFIG.SYS file at startup to configure 
  the DOS system. It is read before the AUTOEXEC.BAT file is run.
  FreeDOS first tries to use FDCONFIG.SYS first (and ignores CONFIG.SYS).
  If FDCONFIG.SYS does not exist, FreeDOS will use CONFIG.SYS instead.
  CONFIG.SYS / FDCONFIG.SYS are text files. They can be created
  or edited with a text editor such as EDIT or EDLIN.
  FDCONFIG.SYS / CONFIG.SYS must ALWAYS be in the root directory of
  the boot media.

Syntax:

  - none -

Options:

  - none -

Comments:

  When booting DOS, you will find it only supports a subset
  of the devices available on many computers. To support 
  additional devices and advanced features, device specific
  driver and memory resident software must be loaded. This
  allows the kernel to be easily extended to support hardware
  not presently available and take better advantage of installed
  hardware without wasting resources on computers lacking it.
  This software is generally loaded during the kernel initialization
  phase, with details describing what to load expressed in the
  file CONFIG.SYS. The FreeDOS kernel will first look for a
  file named FDCONFIG.SYS, should they exist, it will be used
  instead of CONFIG.SYS; this allows the FreeDOS kernel to coexist
  and be configured differently than another DOS kernel. There are 
  additional options available to adjust other aspects of the kernel's
  behaviour.
  There is a special set of commands for use in the CONFIG.SYS / 
  FDCONFIG.SYS file, see the links below.
  DOS prompt and BATCH FILE commands generally cannot be used in 
  CONFIG.SYS / FDCONFIG.SYS. See also the MENU command.
  If you press "F5" while booting up the system, CONFIG.SYS / 
  FDCONFIG.SYS and AUTOEXEC.BAT commands are ignored.
  This is helpful if you have a driver installed which crashes
  while booting up the system.
  If you press "F8" while booting up the system, each command in 
  CONFIG.SYS / FDCONFIG.SYS and in AUTOEXEC.BAT has to be
  confirmed with "yes" or "no". This is helpful if you want to
  find out which driver crashes.

Examples:

  - none - look for the single commands.
