10.5: Install on a PPC Mac from an external USB Drive
Authored by: hdhu on Jun 17, '12 04:50:30AM

hey guys!!!! after a few tries, I FOUND A SOLUTION. my powermac G5 is now on the nice 10.5.6 :)))
HERE'S A GUIDE FOR ALL THOSE OF YOU, WHO ARE STILL STUCK WITH THE GUIDE ABOVE:

1. if you are completly new and have no torrent downloader, download vuze. its a nice, small, free torrent downloader and it works :)

2. after that, you have to download the iso file. i chose the one on www.picktorrent.com/download/b7/173126/mac-os-x-leopard-10.5.6-full-retail/
it should work...
if everything is done, a folder "vuze downloads" should appear on documents. open it and go to mac os x install dvd. inside should be a dmg file.

3. plug your USB stick (8GB, better more) into the computer. the file system should be set to MAC OS X EXTENDED (NOT journaled)

4. follow the guide above from step 3 til step 8.

5. you're now in open firmware. type in dev / ls and a list with all files will appear. press space to scroll down. now, you have a tree structure, you have to choose the leftest and go to right and bottom, till you reach
/usb@b
/disk@2

(it don't have to be exactly like that)

then write down the whole path
(in my case ht@0,f2000000/pci@8/usb@b/disk@2)

6. write devalias into the command prompt. it should appear a list. you have to search the USB. (in my case USB2,USB3,USB1a,USB1b,USB1c) then I guessed that it would be USB2.
my choice was the right, if your one isn't the right it will nothing happen in step 7.

7. type dir (name_found_in_step_6)/(disk_name_found_in_step_5) :(partition_number_found_in_step_7_of_the_guide_above),\System\Library\CoreServices (in my case dir usb2/disk@2:10,\System\Library\CoreServices)

8. now a list should appear with the programs inside this folder. if a program with the name BootX and the atribute tbxi is there, you're almost done. type in boot (name_found_in_step_6)/(disk_name_found_in_step_5) :(partition_number_found_in_step_7_of_the_guide_above),\System\Library\CoreServices\BootX

9. press enter. the installation should now begin.

10. ENJOY YOUR FREE LEOPARD!!!!! :D

so it worked for me. i hope for you, too and for questions just ask me: fritzmeier83@gmail.com

(PS: sorry for my bad english, i'm from switzerland :)

10.5: Install on a PPC Mac from an external USB Drive
Authored by: restless on Dec 07, '12 01:43:42PM

I'm on a powerbook 1.33 GHZ with a burned firewire and need to upgrade to leopard.

I am using an external USB drive 8 GB with only Leopard on it (partition 10)

I did a pram reset.

in OF my disk pattern is pci@f2000000/usb1b,1/disk@1

By "devalias"the above pattern corresponds to usb0

following the post to my case I get

dir usb0/disk@1:10,\System\Library\CoreServices fails ..

any help !?

thank you

Uhm... that's strange, did you try out also the guide of ruth gaudi? If nothing works, it could be cause of the powerbook... this guide is for a powermac and I dunno if it works on a powerbook, too. I don't own a powerbook so I can't try it out... I'm very sorry, ask google for how to upgrade a POWERBOOK to 10.5, I can't help you :(
