I want to be able to boot into both Jaguar and Panther. Is this possible? I'm sure this question has been addressed in the past... so if you have a link to the thread, that would be great as well.

Thanks,

On the same hard drive, I don't believe so. (Reason being, a lot of the files in the two systems have the same name, so obviously they couldn't reside together.) But you can definitely do it on two different hard drives.

You could do it on the same drive if you partitioned it. However, this would erase everything currently on the drive.

I have 2 HDs, and 5 bootable systems (3 OS X, 2 OS 9).

Is there website or guide I could refer to on how to partition a Mac hard drive and installing the different OS's?

No need for that, I can easily guide you thru it...

But, first, I want to be certain that you understand that partitioning your HD makes it into two seperate drives, and will ERASE EVERYTHING on it. You understand this, correct?

To partition the HD is extremely simple.

First, you have to boot from the first OS X install disk (Panther or Jaguar, but I suggest Panther). Then, let the installer load, but DO NOT begin the install. Instead, go up to the "Installer" menu and select "Launch DiskUtility"

From there, select your HD (should be the very top selection) in the left column. Note: you want to choose the actual drive, not your volume (MacintoshHD, or whatever you've renamed it, is not what you want).

Then, click the "Partition" tab in the upper center of DiskUtility's window.

Under "Volume Scheme:" is a drop down menu. Select how many partitions you want.

From there it's pretty straight forward. Just look at the graph, and you can drag sliders to adjust the size of each partition, and name them there as well. Make sure the first partition is at least 8GB.

If you can and want to boot into OS 9 from any of these volumes (partitions) make sure to check the checkbox to install OS 9 drivers.

When you have it all set up and ready to go, click the "Partition" button in the lower right corner. It will be a pretty quick process.

Then, I'm not sure exactly what happens from there, as it's been awhile since I did it, but it should be pretty straight forward. I think DiskUtility will let you know when it's done, and you just quit it and it'll go back to the installer.

Once back to the installer, go ahead with the installation of OS X, because you will now have an empty disk with no OS to boot from. You will see both of your newly created partitions as installation destinations. Pick the one you want to install Panther on, and go on with the installation.

Then, when that's all done and over with, boot from your Jaguar disc and install it on the other partition.

That should be all there is to it.

Isn't there an issue when running 2 different versions of OS X on 2 seperate partitions? I'm sure there was a problem when it came to launching applications which existed on both installs, but are different version numbers.

Yup...I know. I was just saying you can't do it on the same partition.

Yes, it can get a little weird like that. I shoulda mentioned that.

I don't know a great way to put it into words....

For example, if I double click a ".prefpane" file, it will open the System Preferences app from a different installation. This can often be fixed by selecting the file, Getting Info on it, and reassigning the Open With app.

But, if I already have the correct System Prefs app open, and then double click the file, it will open in the open, correct, System Prefs app.

Does that make any sense!?

Thanks! This has been really helpful. I'll give it a try.

Sure does. For a short time, I had Panther on an exernal drive to test before putting it on the main drive. I'd be trying to open Preview, or Textedit in Jag, only for it to try and use those programs in Panther.

Keeping an OS X install on each partition works fine, I've been doing for years.

As noted, there may be issues with the wrong application being launched when you double click a document, because by default the OS wants to run the *most recent* version of the associated application. So you might get Panther's TextEdit when you double-click a text doc in Jaguar.

Sometimes this is not a big deal, and sometimes you'll just crash (because some Panther apps will not run under Jaguar.)

The work around I use is to auto-unmount the other partition upon login. See here for a shell script:

which you can rig to run from an Applescript upon login, and manually when you want to switch partitions before rebooting.
