Command: F8 button

  Executes each single line in CONFIG.SYS / FDCONFIG.SYS AND
  AUTOEXEC.BAT / FDAUTO.BAT by asking you if you really
  want to execute it.

Syntax:

  - none -

Options:

  - none -

Comments:

  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 as it stops at the bad driver or
  command.
  F8 is a command internal to kernel.sys and needs no other file
  in order to work.

Examples:

  FreeDOS crashes while executing config.sys / autoexec.bat every
  time. You have no chance to change something as this happens at
  each bootup.
  Press F8 while booting (kernel message is shown), then each driver
  in config.sys and each command in autoexec.bat is executed step by
  step. So you can check each single driver / command step by step
  and can choose "NO" if you know which one should not be loaded.
  The machine boots without this driver / command and you can fix the
  problem by editing config.sys / autoexec.bat. E.g.:
    DOS=HIGH[Y,N]
    DOS=UMB[Y,N]
    SHELLHIGH=C:\FREEDOS\BIN\command.com C:\FreeDOS\BIN /E:1024 /P
      /P=C:\FDAUTO.BAT[Y,N]  etc. Simply press Y or N button.
