Hi Walter, Technically, you should be able to install Leopard on the late model 1.25GHz G4 iMac.
License-wise, unless you got the family pack, you are only licensed to install it on one machine (either the G4 or the intel but not both). As far as I know, Apple doesn't have any active software measures to stop you installing it on two machines - it's an honour system. If you actually want to run Classic apps, you should stick to Tiger. Regarding the Tiger upgrade DVD - I think that it will probably check for an appropriate existing system before installing - if it can actually "see" the existing Tiger system on your hard drive (even though it's not booting) you MAY be able to run an erase & install directly over the old system. I would think the easiest way would be just to try - the installer should tell you if it needs a prior system present that it can't find. Cheers Neil -- Neil R.
