If you are running a dual-boot system using Windows NT 4 and Window 98, you will need to maintain your C: drive as a FAT16 drive (or partition). This is necessary for the Ntldr (NT Loader) to function correctly.
Also, you must keep in mind that any FAT32 drives or partitions will be functionally invisible to your Windows NT 4 system, and any NTFS or HPFS drives or partitions will be functionally invisible to your Windows 98 system.
Now that you know about the environment you are designing your applications to run in, you are ready to start building those applications. In the next chapter, we’ll begin by constructing two simple applications: a Windows version of the traditional ‘Hello, World’ demo program and a template application that can be used as the basis for other applications.
