I bought a used G4 and it has OS9 installed on it under OSX 10.5 im gonna reformat the HD soon. When i reinstall Leopard will OS9 install too? minus and apps or files on it?
 
Leopard killed Classic entirely. You'll have to go back to Tiger to run OS 9.
I think that it is clear from the circumstances that the OP can run MacOS 9 just fine if he boots into MacOS 9. However, he cannot run Classic unless he boots into MacOS X 10.4.x.
 
so i need sheepshaver?

No, you would need only OS 9 to re-install it on the drive after formatting. If you want to run OS9 apps in OS X, you'll need sheepshaver or go back to 10.4, which also would need OS9 to run in Classic.
 
i took pics of the current setup, does this make sense? please explain it to me. maybe he upgraded from os 9? how can i boot to it?

You should be able to boot to the OS9 install by selecting it on the Startup disk window and clicking Restart, or by holding Option when you hear the Apple bong at boot.

If you re-format, you probably need to install OS 9 first, then OS X.

hmm any guides on how to install it? along with osx?
 
Also, no version of OS X ever came with OS 9. They came with Classic, which requires you have OS 9 already.

Nope. When you install Classic it installs OS 9.2.2...you don't need to have it already. Otherwise my G5 wouldn't run Classic.

yeah. came with it. at least the OEM bundle that came with my G4 quicksilver.
Yes. Early versions of MacOS X also shipped with contemporary versions of MacOS 9. MacOS X 10.0 shipped with a full-installation CD for MacOS 9.1. MacOS X 10.1 shipped with a full-installation CD for MacOS X 9.2.

You can use Cmd-Shift-3 for full-screen screenshot and Cmd-Shift-4 for screenshotting only a selected area. Press Space when using the second shortcut and you can capture only an object your mouse will point at.
 
So i need to install OS 9 First and then OSX? How do i do this? make seperate partitions?

Ive been a PC guy for many years now and i have done dual boot setups, would i follow the same guidelines as i do with PCs?
 
You don't need separate partitions, the two OS's can co-exist on the same drive.

I can't remember if there was a way to install OS 9 after installing OS X, but if you're reinstalling both then it'd be easiest just to install 9 first anyway.
 
If you reformat, and don't click on the advanced settings to select OS 9 bootability ... you won't be able to use OS 9 with leopard.
 
Out of curiosity, what do you need OS9 for? It would save you a whole lot of headache not to install it, after all... It kind of seems like your computer came with OS9 on it, and you want to have it again just because it came like that...
Just curious :p
 
old games, i love Marathon and EV... miss them too much!

If you just want OS 9 for games, SheepShaver might be a more convenient solution than having to reboot to play games and then reboot back to Leopard. Those of us on Intel machines had the decision made for us... no classic mode or native OS 9 boot, so SheepShaver was the only option even under Tiger.

Either way you go, do you have the OS 9 install disks?
