Hello - my first post, so please be indulgent. I have a G3 Pismo PowerBook, running Mac OS 9.2.2. The CD-ROM/DVD never worked very well, and eventually it gave up the ghost completely a couple of months back. (In case anyone knows how to revive it, it was making mrr mrr noises and apparently just spinning the CDs, and the system would freeze when I put a CD into it. Many, many restarts.) I also have an external CD-RW, an Iomega Predator, connected by USB. Someone told me yesterday that it's actually possible to use this as a boot device, if I find the keyboard shortcut for "Target Disk". I can't seem to find this, and wonder if he were right. Does anyone know if it is possible to boot from an external USB drive, and if so, how? This is particularly important to me because I'm going to be selling the PowerBook and the external CD-RW, and would be a lot happier if the buyer were going to be able to reboot, run system software and run doctoring software, if the machine runs into any trouble.
