System Requirements
Upgrading a NetBoot image to Mac OS 9 requires:
-
Mac OS X Server 1.0-2 (or Mac OS X Server 1.2)
-
Mac OS 9 CD
-
NetBoot Desktop Admin 1.1 recommended
Note:
If you are using Macintosh Management Server, upgrade to version 1.2 or later of this software, available from the Apple Software Updates Web site at
http://www.apple.com/swupdates
.
Introduction
Early versions of Mac OS X Server came with Mac OS 8 NetBoot images. It is possible to upgrade these images to Mac OS 9.
Note:
If you wish to NetBoot an iBook, iMac (Slot-loading), or Power Mac G4 computer, you must upgrade your NetBoot image to Mac OS 9 or later.
Summary of Upgrading the NetBoot HD Disk Image to Mac OS 9
To upgrade the NetBoot HD disk images to Mac OS 9, you have to log on to a NetBoot client computer, connect to the NetBoot server volume, and open the NetBoot Desktop Admin program several times. You must also have a Mac OS 9 installation CD to upgrade the image. Changes are not available to you or other users until after the NetBoot client computer restarts the last time.
Before You Start
Before you start, you need the following information:
-
Name and password for a Global Administrator who belongs to the System Access workgroup.
-
Name and password of the root user.
-
Make sure that no users are NetBooting during the upgrade procedure.
Performing The Upgrade
To upgrade the NetBoot HD disk image to Mac OS 9:
-
Log on to a NetBoot client computer as a Global Administrator who belongs to the System Access workgroup.
-
Mount the NetBoot Server volume. Open the NetBoot Desktop Admin application.
-
Using NBDA, increase NetBoot HD.img image so that there is at least 250 MB of free space. You cannot reduce the size of an image without reverting to a backup copy.
-
Click Make Private Copy. NetBoot Desktop Admin creates copies of the disk images that you can change. This may take several minutes and you should not interrupt the process. When it finishes, your NetBoot client computer restarts automatically.
-
Important:
Because the copies of the disk images are associated with the NetBoot client computer you used to create them, you must make the changes to the images using the same computer. If you change computers, you will not be able to see the changes you have made and your changes will not be available to users. In addition, you increase the risk of unauthorized persons making changes to the disk images.
-
Log on to the NetBoot client computer again as the same user.
-
Using the Chooser on the client, locate and mount the Mac OS format volume on the Mac OS X Server on the client. Log on as a user with read and write access privileges (for example, the Administrator of the Mac OS X Server).
-
Open the volume and locate the Shared Images folder.
-
Locate the Mac OS ROM file and change its name to something other than Mac OS ROM. Do not throw it away, you will need it later.
-
Insert the Mac OS 9 CD.
-
Locate the System Folder on the Mac OS 9 CD. Open it and locate the Mac OS ROM file.
-
Drag the Mac OS ROM file from the Mac OS 9 CD to the Shared Images folder.
-
Open the Mac OS 9 installer and install an upgrade on the NetBoot HD. The client will restart after the upgrade. If the NetBoot HD is not set as the startup disk, hold down the N key to make the client start up from the NetBoot HD.
-
After the restart, the client will start up the Mac OS 9 Setup Assistant. Do not use the Setup Assistant. Choose Quit from the File menu. If you have other upgrades to install, do so at this time.
Important:
Before you finish customizing the NetBoot image, be sure to install the latest version of Macintosh Manager client software, available from Apple Software Updates at
http://www.apple.com/swupdates/
. Then be sure to use the Multiple Users control panel to turn on Macintosh Manager and choose "Macintosh Manager account (on network)" in the Options... Other tab.
-
Using the Chooser on the client, locate and mount the Mac OS format volume on the Mac OS X Server on the client. Log on as a user with read and write access privileges (for example, the Administrator of the Mac OS X Server).
-
Locate the Shared Images folder and open it. Locate the Mac OS ROM file and name it something else. Locate the Mac OS ROM file you renamed in Step 8 and change its name back to Mac OS ROM.
-
Open the NetBoot Desktop Admin utility. Locate the System Folder and open it. Locate the Recent Documents, Recent Applications, and Recent Server folders and drag the contents of each folder to the Trash. Then close all the windows except for NetBoot Desktop Admin. Save the changes in NetBoot Desktop Admin. Note that this step prevents the user from seeing the various installers and other applications that were run during the modification of the images, but it is not a mandatory step.
-
The client restarts, this time using the operating system version you were upgrading from.
-
Open the NetBoot Desktop Admin utility one last time, and save changes.
-
When the client restarts, it should restart with Mac OS 9.
-
Verify that the file named Mac OS ROM in the SharedImages folder is the correct version for the version of Mac OS just installed. You can do this by selecting it and choosing Get Info from the Finder's File menu.
