Fedora 4
 

I have an old pc which supports older versions of fedora , i tried searching on torrents and google . i couldnt find any older versions such as fedora 4 or fedora 5 , where can i download it from ?

Try googling fedora core 4 download, enough results, here is one:

But why core 4 or 5? When installing you can set what you want to install, so I guess core 8 or 9 would work fine also?
