Help imac g3 wont boot

Hey I tried to boot into os 9 with my imac g3 and now it wont boot. It has an os 10.1.5 partition and a (corrupt) os 9 partition. When I try to boot up the mac I don't get a chime. It shows a finder folder on the screen for about 5 seconds then goes to a question mark floppy disk. I can get to the developers command line thing but thats it. What should I do?

plz help!
