How to format a imac 233mhz with mac os x 10.0.3 cheetah?

[tgg]

All I want to do is format the drive and isntall mac os 9.1 fresh. Like with regular pc u just put the floppy disk and format is this possible with the mac os x imac that i have?

If you have the Mac OS 9 CD, insert it into the CD rom, restart and hold the "c" on startup. It will boot into the Mac OS 9 startup disk, which will have some utilities on it for wiping your hard drive, and then you can install from there.

Duff-Man says...if you are having trouble booting from other disks other than the defined start-up disk (and from your other somewhat confusing threads it sounds like that may be the case) then try zapping the pram by holding down Command+Option+P+R at bootup - let it "bong" a couple times...then boot from a Mac OS 9.x cd and use the Disk Utility program (it is called something like that - its been a while since I've used OS 9) to reformat the drive....oh yeah!
