You have a couple of options. If you have the latest version of OS 9.2 installed (and you can boot off of it), the copy of Disk First Aid in the Utilities folder does the same thing. If you want to (or need to) do it off of the OS X Installation CD, boot up as you are. Once in installation mode, go up to one of the menus on the left (either the Apple menu, Application menu, or File menu), and there is an option to open Disk First Aid. You should be able to go from there.
