Jelena Mamčenko Operating Systems Lecture Notes on Operating Systems 59 information that is used to change the operating system for personal use. They also contain the requirements of different software application packages. A DOS system would require troubleshooting if either of these files became damaged or corrupted. CONFIG.SYS is composed mostly of name=value statements which look like variable assignments. In fact these will either define some tunable parameters often resulting in reservation of memory, or load files, mostly TSRs and device drivers, into memory. In DOS, CONFIG.SYS is located in the root directory of the drive from which DOS was booted. In some versions of DOS it may have an alternate filename, e.g. FDCONFIG.SYS in FreeDOS, or DCONFIG.SYS in some versions of DR-DOS. Both CONFIG.SYS and AUTOEXEC.BAT can still be found included in the system files of the later Microsoft Windows operating systems. Usually these files are empty files, with no content. OS/2 did not use the autoexec.bat file, instead using startup.cmd.
