you have to connect a cdrom drive (they are cheap these days) or if you have a laptop buy a
cf to pcmcia adaptor and a card flash more than 512mb and copy at the laptop the files from cd to the card flush and then to the amiga hard disk. then install. this method is more expencive than to bye a cdrom dive though... but you can use it to transfer files from amiga to laptop and back in general use.
