Operating systems are rarely designed to peacefully coexist with one another. Installing a new operating system (OS) often leaves your existing OS unusable. System Commander protects your existing operating system from the predatory nature of new OSes. With System Commander you can keep your existing OS, like DOS and Windows 3.11, and have other OSes like Windows 95/98, OS/2 Warp or Linux on your PC!??System Commander provides the most cost efficient way for multi-platform developers to build applications on multiple OSes. Technical support engineers save substantial time and money duplicating caller configurations as quickly as they can reboot. Training facilities save numerous hours switching PCs to a new operating system or network OS by simply rebooting the systems. Instead of investing thousands of dollars in more PCs, System Commander makes it easy for you to have any combination of PC-compatible OSes on a single PC.
