Shit! I ran the installer and the machine hung on a blue screen for hours. Although some sites said to wait for 2-3 hours for it to resolve itself, I tried that and it totally didn't work.
I finally had to dig out the original install discs for the PowerBook and reinstall Panther. Doing some more searching, I found a command line hack that is supposed to resolve this issue, so I guess I'll try it tonight and see if that makes it work or not. I've held off on upgrading my G4 Mini as I'm a little gun-shy about upgrading the non-Core chipsets.
Stay tuned -- I'll update with full instructions if this works tonight.
<-- I can see them on my MacBook Pro, but not yet on my Powerbook.
UPDATE: Ok, so I fixed this and here's how:
- Inserted the Leopard DVD
- Chose the customized install option and chose the option to archive the previous system
- Ran the install
- Went to the blue screen
- Hit cmd+opt+esc a bunch of times, which finally brought up the force quite dialog
- System was hung on the registration application (strange)
- Once the force quite dialog came up, then the registration application started running, so I simply canceled the force quite dialog and everything worked fine
- Got to the desktop, tested some stuff, and deleted the prior system
- Ran software update and downloaded and updated everything
- Restarted and checked stability
- Trashed the old system
The Mini gets upgraded this evening.
