    Just thought I would share (may help others)

    -Installed leopard to 12" ibook G4 1.2GHz 512mb mem
    -Used "super duper" to clone to ssd external enclosure
    -External ssd plugged into left closest to front usb port
    -Open disk utility and click on ssd on left pane (probably called "untitled") and pick "information" and write down what it says for "disk identifier"...mine was disk1s3
    -Reboot ibook and boot into "open firmware" by holding down Command Option O+F
    -now to get ssd to boot type (without quotes) "boot usb0/disk@1:3,\\:tbxi" and hit enter

    note: you may have to place the "3" in the line above with whatever number you came up with from "disk identifier final digit"

    couple extra notes:

    -after using the external usb ssd hd for a few days it definitely seems snappier....the ibook loads programs faster and even internet browsing gives less lag when scrolling.

    -i made a usb boot stick of osx leopard dvd and used above method (in first post) to boot from it and do a clean install,and works great.

    Almost there, but when I enter:
    "boot usb0/disk@1:0,\\:tbxi" and hit enter, then I get:
    "load-size=0 adler32=1"
    I can't for the life of me figure out how to increase this load size. Any help would be great. Thanks!

    Literally have my 12" PowerBook G4 1.5GHz, 1.25 GB RAM copying it's hard drive over to a 64GB mSata SSD right now. Looking forward to testing it out and then replacing the hard drive which sounds like it is on its last legs. Thanks for the added information!

    0 does not strike me as a valid partition number (in the disk@1:0 part). Is that really what you see when you use disk utility to check the disk identifier for the partition in question?

    The problem with iBook G4s is that they don't have the "ud" devalias in OpenFirmware (at least my late 2004 model doesn't). In my case as well, usb0/disk@1 is the correct alias for the USB port closest to the front of the laptop.

    A bump for sucess :D

    Using SuperDuper! I created a backup of my PowerBook G4 to an external powered USB drive.

    Using the above command with a change for the second USB port (boot usb1/disk@1:3,\\:tbxi) I was able to boot from the backup.

    Thanks for posting this, I now have a backup solution for the PowerBook.

    I'm just going to note here something interesting I've found.

    I have a USB 2.0/FW400 PCI card in my QS. I am able to boot directly from a USB stick attached to my card using the boot loader (the one you get when you boot holding down the OPTN key).

    Because it scans the bus it takes a while for the USB stick to be recognized, but it boots just fine. No Open Firmware involved for me.

    Why this works, I don't know but it's only with items attached to my USB card. Further note, that when booted the USB stick is not recognized as a boot drive under Startup disk in System Preferences.

    It's an odd thing, but I'll take it. :D

    Today while hardening the Leopard install on my PoweBook I trumped it really bad :(. Using the information from this thread, a recent backup on a USB drive and SuperDuper I was able to restore my PB :D.

    Maybe something to do with USB 1.1 vs the USB 2.0 the PCI card has?

    I've been told since then it has something to do with the version of the USB controller as compared to later Macs.
