"Hardware" Panel in System Profiler Gone

Recently I reinstalled mac OS X 10.4 Tiger on My iBook G3 12" 800MHz after changing it's hard drive. In system profiler, there used to be a tab called "Hardware" with the logo being a picture of a PowerPC CPU and would give you some options on controlling system cache, now, after reinstalling the OS, it's gone. I used the same install disks as the ones that I used to install tiger a few years back on the machine. How do I get the panel to show up? is it an additional install, or a seperatly downloaded program?
