Does windows 9x still reliy on DOS routines to load?

Yes, Windows 9x (including Windows 95, 98, and ME) relies on DOS routines to load and operate. These operating systems are built on a hybrid architecture that integrates the Windows graphical user interface with the underlying DOS environment for tasks like file management and hardware interaction. While Windows 9x can run in a graphical mode, it still uses DOS for booting and executing certain low-level functions. However, it is important to note that newer Windows versions no longer depend on DOS.
