Install said program, then right click on the shortcut that starts the program and click on properties. then click on the Compatibility Tab and click on Compatibility mode and choose one, windows 95 or 98/ME would work probably. To boot windows in dos mode, Hit the F8 key before windows boots up and then choose windows in command prompt only. In windows XP you should not have to use the files and buffers, but if you do then just create a config.sys file in the root of windows and enter your settings there. Or you could right click on the my computer icon and then do properties and then click on the Advanced Tab and then click on Environment Variables and enter the info there.
