Hi folks, this is just a quick request for info about _your_ iBook's optical drive. Can you take a moment and open System Profiler, copy the info about your machine model, plus the optical drive info, and paste that into a reply either here or directly to me (or both :-) at macdan at comcast dot net I'm especially interested in the cd-rw, dvd-rom, and combo trayload mechanisms installed into iBook models from the clamshells up to the last of the G3s. I'm building a knowledge base to facilitate optical drive upgrades. I've already published a similar page about PB expansion bay module upgrades <http://mywebpages.comcast.net/macdan/ebms.html> Many TIA, Dan K ................................. http://macdan.n3.net/ carracho://dankephoto.dhs.org:9700 hotline://dankephoto.dhs.org:9500 .................................
