I have a 400 MHz TiBook that runs Jaguar 10.2.3. I'm trying to set up an emergency boot FireWire utilities disk, using the 2.5 inch 10 Gbyte drive that originally came in the laptop. I purchased a case/power supply combination (it uses the Oxford Bridge Chip). The drive mounts fine on my TiBook's desktop under OS X, and today I installed Jaguar on the newly initialized disk. The TiBook rebooted automatically at the end of the Jaguar installation, but when I held the option key at boot, only my internal boot OS X System Folder, my OS 9 internal System folder, and the OS X installation CD-ROM were listed as boot drives. I started up from my usual system, then opened Startup Disk within System Preferences. Here, the FireWire drive's System Folder showed as a potential boot device. I selected it, restarted, and briefly saw the question mark folder before the TiBook booted from its internal drive. The disk activity light on the FireWire drive glows and doesn't flicker until AFTER the boot process starts from the internal drive. I can't find anything on Apple's website, the OS X help system on my TiBook, or on the XLR8yourMac website that discusses why my new OS X 10.2 system on my FireWire drive won't boot the TiBook. Any ideas? Is there something I need to do to make the device bootable? Thanks so much, Jim Robertson --
