OSX Tiger and iBook G3 help!

I just bought an old iBook G3 off a friend, which has been wiped clean. Absolutely nothing on this machine.
I inserted my OSX Tiger cd, that I got with my iMac G5, into the iBook and received a message on screen saying:

"Alert

This software cannot be installed on this computer. "

Can anyone tell me how to get around this, or what OS version that is capable of running on my iBook.

Thanks.

Sorry I've posted this in the wrong board!
Can one of the mods please delete it.

Sorry again!
