Right person to discuss this with is ThoR who no longer works on OS. The installer should detect what hardware it is being installed on and ask for modules disk accordingly, the detection of hardware use same code as LoadModule. Of course this only works if you actually perform the installation on a CD32 and not UAE with A1200-like settings. Only a few modules are system dependent and the way LoadModule works, you can have them all installed on same boot media… I don’t grasp why they didn’t opt for just doing that as default.
