I've succesfully reinstalled my Orange Micro into my souped up 7500, with a PowerLogix G4 450mhz card and 584MBs of 60ns RAM. I notice on the Apple System Profiler that the USB ports are recognized, in addition to the card as a 4-port hub. Does this mean that the Firewire is also enabled even though they don't show up as Firewire ports on the system profiler?
