I recently got an iMac G3 (fully working!) For $20 from my friend, though he didn't have a keyboard or mouse for the computer. So I used just a generic keyboard that I had laying around. Everytime the computer booted into Mac OS 9, it would freeze after a while. I put a new HDD in it, and tried to boot to a CD by holding the D key on startup, but it did nothing. And when I had the old HDD in it, which had Mac OS 9.2, and Mac OS X 10.3.9, I would try to hold Win(Command), Alt(Option), O, and F, to enter the boot list, but it wouldn't do anything. Do I need the original keyboard to do these options on Boot?
