Booting from a USB drive

Modern Intel-based Macs can boot from USB, but you will encounter some difficulties when you try this method on a iBook G4 or PowerBook G4. When you buy a OSX Panther or Tiger license you'll get DVDs by default - this is a problem when you have to install 10.3 on a 300MHZ machine which has only a CD-Drive and no firewire port. But the Clamshell iBook is able to boot from USB if you've got the right drive:



The Developer Note for Apple iBook from 1999 stated on page 30:

"The Macintosh USB software supports booting from an external USB storage device"

Indeed, my 300MHZ Blueberry iBook booted via USB from a Philipps LightScribe DVD-burner which is in an external 5.25 " NoName enclosure with USB and FireWire ports which has a Prolific PL-3507 chipset. But my new USB 2.0 Freecom FS-50 burner was not considered as a boot device by the Clamshell Boot boot menu which shows up when you press ALT right after powering the iBook. So the clue to the problem is a USB 1.1 compatible chipset - you have to try it out. If your external DVD drive is bootable, drop me a line and i will post a list later on. http://www.prolific.com.tw/eng/Products.asp?ID=9

The iBook will almost certainly bring a seachange in our perception of computing. For all the analysis and pontificating about the iBook's capabilities, the primary driver of the new laptop's success will be it's unique style and the portability to put that style in the face of the public.
