Mac OS x Problems/Installation


Lo all,
I have an iMac at home (one of the ones with the blue plastic round the back), and I've just got panther for it. When i try to install panther, it goes all funny and asks for some sort of missing firmware. At the moment I ahve mac os 9, is there any way to fix this? The IMac isnt connected to the internet, but i do have PC's that are, can I download this firmware and then transfer it from PC to Imac?
