OS/2 Version 2.0 provides the capability to support multiple operating systems on the same machine, by providing an operating system independent boot utility known as Boot Manager.
For example, OS/2 Version 2.0, DOS and AIX may be installed on the same physical machine, using separate fixed disk partitions and/or disks as supported by Boot Manager. When starting the machine, a user is presented with a panel allowing selection of the required operating system. The partition which contains the desired operating system is then activated, and that operating system is loaded and started.
