FreeDOS reads the config.sys file at startup to configure the DOS system. It is read before the autoexec.bat file is run.

There is a special set of commands for use in the config.sys file.
DOS prompt and batch file commands generally cannot be used in config.sys.

Making config.sys interactive with ! and ?

Config.sys lines that begin with ! will be processed even when single stepping.


Lines that begin with ? will be queried: the user will be asked for confirmation before that line is run.


See also the menu config.sys command.
