I did quick research on the Internet and could not find a simple way of doing this aside from the usual forum best advice… I had tried to mount the PowerBook on my iMac Core Duo using a FireWire cable and “T” for target and then installing the system off the iMac’s drive with the PowerBook as the target installation drive.

Much to my dismay, Leopard’s Dr Jekyll and Mr Hyde, Universal Binary installed an Intel personality on my perpetually “? booting ” PowerBook.

The solution was to mount a MacBook as a target Firewire drive on my PowerBook and boot the PowerBook using the”Alt”key to find a volume with an OS that would be the Leopard disk inserted in the MacBook’s DVD drive. Wow, how geeky can it get? I was running out of fingers, keyboards and wires. Are you up on your keys?

Here is a good primer for you:
On boot up  
hold the C key to start from CD 
hold the T key to put computer in FireWire Target Disk mode
hold the ⌥ key to show all startup disks 
hold the ⌥⇧⌘⌫ to start from external drive or CD

In the Finder
Pressing ⌃⌘-power will restart
Pressing ⌃⌥⌘-power will put computer to sleep
⌘-tab cycle forward through applications
⌥⌘-esc Force Quit Applications dialog
⇧⌘3 screen dump (entire screen)
⇧⌘4 screen dump (drag a rectangle)
⌘-space Spotlight

There is a lot more on the rixstep web site. They are programmers who chew UNIX like we chew gum. They make a couple of practical programs that they release under a suite. They are known for XFILE and CLIX that I had fun using for clearing caches. Check out Spike if you need a “real” file shredder. Outbox sounds like a very practical mailing application.

The main argument for their approach is that you should take control of your data, including hidden files. It makes sense to me. Revealing iPod_Control for example might be useful if you got your computer stolen and were left with your iPod as consolation.
