Heres a little info for you if you can not get it to install try a program called XpostFacto. Its on the Otherworld website (Mac reseller) This should take care of any problems you run into getting it to install. Now here is some more just FYI info for you;
XPostFacto will allow you to run OS X on any Legacy Mac (Power Mac 603 and up) They have installed OS X on the Powerbook 3400 even. I tried it also with a G3 upgrade and it works really really well. Panther is in development but they do have a working beta. I could not get it to work with my Power Mac 9350 Workgroup server which I upgraded to a Sonnet G3 400 1MB. I would recommend though that you have a little bit nicer graphics card on the Legacy's then stock.
