All you need is another bootable partition. I have DH0: (3.9, default), MOS: (MorphOS) and OS4: (OS4) on my machine. Use the early boot menu to switch between them. For OS4, it's very helpful to set the BootDevice kickstart module to force booting from the OS4: partition. Otherwise, after the OS4 modules are loaded in the machine will try to boot from the 3.9 partition (based on boot priority numbers), yielding some very unstable results.
