Re: USB 2.0 boot on 15" PowerPC Aluminum Powerbook (Model 5,6)

 Thanks for the reply. I ended up getting it done, without firewire at all. 
:p 

I neglected to mention in my first post that I had a USB => 2.5" IDE cable. 
I also didn't have another Mac. Thirdly, I definitely didn't mention that 
the Leopard installer does not run from within Tiger (if it did, I could 
have installed it directly onto the drive and swapped it in.) And even if 
you do copy the image from the DVD to a USB stick, mount it, and run the 
installer, it will tell you have to reboot, and it _will_ reboot. (right 
back into the old OS you came from, if your model doesn't USB boot :p) 

In case anyone was interested, (I may post it to my blog if anyone finds it 
useful) this is how I did it: 

1. Used the current install on the laptop (Tiger, 10.4.11 PPC) to format the 
new drive (with the USB => 2.5" IDE cable) 
2. Created two partitions on the disk I planned to install into the laptop. 
3. First partition was empty (HFS+ journaled, case-insensitive), second 
partition at end of disk was 7.5 gigs (install DVD was 7.2 or so) 
4. Used "Disk Utility" to restore the "Mac OS X Leopard Install DVD" image 
I'd created (directly from the install disc) to the second partition, at the 
end of the disk (still within Tiger) 
5. Used "bless" from the Tiger install to ensure the machine would boot up 
the install partition, located towards the end of the drive. (This step may 
be unnecessary, as I made a backup through "Disk Utility" which probably 
should have preserved boot info, also I assume that the "Leopard Install 
DVD" is probably "bless"ed (in the command-line sense) by a release engineer 
at Apple (but probably with a newer version.)) 
6. Shutdown the laptop whose HD I wanted to upgrade, replace it with the new 
one (with the install image at the end.) 
7. Powered on the laptop, which started the Leopard install. (Although the 
disk seeks like crazy, it gets the job done. It didn't take more than an 
hour.) 
8. Updated to 10.5.3, and then deleted the install partition at the end of 
the (now internal) hard disk, did you know HFS+ has an online resize as 
well? (no need to reboot, woot!)
