Hello, TaifunBoot v1.7 is posted to comp.binaries.apple2. It's a program that let's you install multiple prodos-based operating systems (GS/OS, P16, P8) on the boot-partition of your hard-drive. Also, there is a configuration menu for GS/OS and P16 that let's you change the state of each Init/FX/DA/Driver/FST (active/inactive) before you boot the system. have fun, Jesse Blue / Ninjaforce
