installing Leopard on PowerBook

No- it should be fine, as long as you're not talking about Snow Leopard. 10.5 is perfectly compatible with PPC Macs. If I were you, I would make sure to max out the RAM.

 

As long as your CPU is 867 MHz or faster otherwise it isn't quite as straightforward.

 

1.67MHz? You must be using an Apple I or something.

 

Wow, thats a slow processor, please say that was a typo?

 

your good...try and max your ram (nice and easy on powerbook)

 

You'll be fine, just max the RAM.

 

I am typing this on one of the last model G4 Powerbooks. I have 2 Gigs RAM and Leopard 10.5.8. Things work just fine, no tricks needed. DVD drive reads the Leopard DVD-DL just fine. I installed on a brand new HDD and farmed my old disk out to an external case.

 

There is no 1.65 GHz PBG4. If it's last gen, it's either 1.5 GHz or 1.67 GHz.

 

It can be true, but it should work perfectly normally as your PowerBook is supported. Also, it sounds like your OS is booting in "Verbose Mode" instead of Normal Mode.

 

Take your Powerbook in to an Apple store. Sounds like you might have a logic board failure, i.e. text on the screen. Leopard should install on it just fine, if you have a retail Leopard dvd, not a gray install disc from some other computer. Have the Apple store check your ram too.

 

Nonsense. A logic board failiure wouldnt cause a Verbose Boot ("text on the screen") - It would either cause a kernel panic and stop it booting, or stop the machine starting completely. To the OP, try disabling verbose boot using the procedure in this article: http://osxdaily.com/2007/03/25/always-boot-mac-os-x-in-verbose-mode/. Verbose mode is just an option as Mac OS X is based on UNIX, it in effect lets you see the UNIXy underpinnings of the boot process - its a useful diagnostic tool, but could get annoying if their constantly.

 

That's the one I said doesn't exist

Just giving you a hard time, we all know what you mean

 

You could be right, i was thinking about the "you must restart your computer" screen on a logic board failure.
