Chapter 7: History, Installing and Use of the MacOS 1 Checking System Requirements

Ok, we have covered where Mac OS X comes from; now let us dive into how to make it work. There are two ways you can install Mac OS X:

• On the same partition as OS 9 or
  
  
• On a different partition.

The advantage in installing Mac OS X onto the same partition as OS 9 is that with installation, the system folders for both operating systems will be on the same disk. This is important because any application that uses any system folder items will have to have the exact location of said items during installation.

Here is an example of a possible problem with installation on different partitions:

1. A hard disk has two partitions, named "Disk A" and "Disk B."
   
   
2. The Disk A partition contains the Mac OS 9 system folder.
   
   
3. Mac OS X is installed to Disk B.
   
   
4. AppleWorks 5.0.4 is installed onto Disk A while Classic is started up from Disk A.
   
   
5. AppleWorks 5.0.4 works well when Disk A is designated the startup disk.
   
   
6. The Classic startup volume is changed to Disk B.
   
   
7. When Classic restarts from Disk B, AppleWorks cannot check spelling.

Installing Mac OS X onto a different partition than OS 9 can also have its advantages. There are two key benefits to installing Mac OS X on a different partition from 9.1 or 9.2. If you have compatibility issues, you can still boot to the working partition and repair the folder with issue Protection, in case one partition fails.

In my opinion, it is in your best interest to install on the same partition. In order to install on the same partition, you just follow the walk throughs on the installer disks. However, I do, suggest you turn off all the additional languages and printer drivers, and save almost 1GB of space on your drive.
