Chapter 11. Working with Applications > Running DOS Applications in Windows NT

Running DOS Applications in Windows NT

There are a few methods you can use to run DOS applications in Windows NT Workstation. The method you choose is based on how stringent the requirements are that the DOS application places on the environment. If the DOS application has few requirements for its environment, such as specific types and amount of memory (extended, expanded) available, you probably can run the application directly from the command prompt. Keep in mind that when a DOS application is run from the command line, any settings specified in CONFIG.NT and AUTOEXEC.NT are used. If the application has trict needs from the environment, you should create a shortcut and modify its property sheets to run the application.

Keep in mind that when you run a DOS application from the command prompt, settings specified in AUTOEXEC.NT and CONFIG.NT are used to initialize the DOS environment. This is because Windows NT Workstation uses the settings specified in _DEFAULT.PIF to run a DOS application without a PIF. The _DEFAULT.PIF points to AUTOEXEC.NT and CONFIG.NT as its initialization files.
