Objectives

Given a successful installation of Mac OS X v10.4 on Computer A, you should be able to create a base image of the

Mac OS X installation on Computer B and store it on an external hard drive or on a server.

• Connect Computer B to Computer A

• Restart Computer B in target disk mode (Press and hold the T key while restarting)

• After Computer B restarts and you see a FireWire icon on the display, use the FireWire cable to connect the client computer to Computer A.

• Verify that a FireWire volume mounts on Computer A.

Create a Disk Image with Disk Utility

Use Disk Utility to create an Apple System Restore disk image to store as a backup.

• On Computer A, open Disk Utility in /Applications/Utilties. You should see a FireWire disk and its volume listed in the left column.

• Select New from the File menu and then select Disk Image from Folder.

• Select The FireWire volume of Computer B and click Image.

• In the New Image From Folder window, set the Image Format to compressed and the encryption to none.

• Save the file as BaseImageXmodel in ~/Documents where model describes Computer B (for example, iBook, PowerBook, and so on).

It is a good idea to name your base images to correspond to the model of computer they are imaged from.

• Authenticate when prompted. The image will be created.

• After the image has been created, select BaseImageXmodel from the column on the left.

• Select Scan Image for Restore from the Images menu.

• Authenticate when prompted.

After the image has been scanned, you will have a backup of your master image workstation startup volume that can be used to quickly restore your client computers to a basic configuration.

• When the scan of the image has successfully completed, click OK and quit Disk Utility.

• Unmount the FireWire volumes.

• Shut down Computer B and disconnect the FireWire cable.
