Is anybody else encountering problems accessing Open Firmware main (command line-based) menu? I tried cmd+option+o+f as suggested on the unofficial OS X dual boot guide, but I was finally able to enter that menu by turning on the Mac Mini and keeping the power button pressed.
By the way, new user here (and loooong time Amiga enthusiast), who just got a Mac Mini G4 just to be able to run MorphOS 2.4
