SYMPTOMS

RESOLUTION

To correct this problem:

  • Upgrade to 4DOS version 4.02 or later.

    -or-

  • Set the COMSPEC variable in the AUTOEXEC.BAT file by adding the following statement to the AUTOEXEC.BAT file 

          set comspec=c:\<directory name>\4dos.com

    where <directory name> is the directory in which you installed 4DOS.

    -or-

  • Use COMMAND.COM, in place of 4DOS.COM, on the SHELL statement in your CONFIG.SYS file.
