Jim, Go to this page on Apple's site: http://www.apple.com/macosx/upgrade/ On the right hand side of that page there is a link to this order form: http://images.apple.com/macosx/pdf/tigermediaexchangev2.pdf To exchange the DVD for CDs costs $10. Hope this helps; I thought I better pass it along in case the whole Firewire trick doesn't work out. - Mike W. ta131js wrote: > Hello iBookers: > > My G3/700 iBook has only CD-ROM drive. > So how do I install Tiger on it? > Could I take the Tiger DVD to the Apple store for exchange? > This topic probably has been covered already - sorry I missed it. > > TIA > > Jim
