To create a NetInstall image:

1. Log in as an administrator user.
2. Open System Image Utility (in the /Applications/Server/ folder).
3. In the left sidebar select the image source.

   If no image sources are listed, make sure you have inserted a valid Mac OS X v10.5 or later installation DVD or have mounted a valid Mac OS X v10.5 or later boot volume.

   NOTE: To create an image, you must have valid Mac OS X v10.5 image sources (either volumes or installation DVDs). You cannot create an image of the startup disk you are running on.

4. Select NetInstall Image and click Continue.
5. In the Image Name field, enter a name for your image.

   This name identifies the image in the Startup Disk preferences pane on client computers.

6. (Optional) In the Description field, enter notes or other information to help you characterize the image.

   Clients can’t see the description information.

7. If the image will be served from more than one server, select the checkbox below the description field.

   This assigns an index ID to the image for NetBoot service load balancing.

8. Click Create.
9. In the Save As dialog, choose where to save the image.

   If you don’t want to use the image name you entered earlier, change it by entering a new name in the Save As field.

   If you’re creating the image on the same server that will serve it, choose a volume from the “Serve from NetBoot share point on” pop-up menu.

   NetBoot service must be configured on a network port and Server Admin must be set to serve images from a volume for this option to appear in the pop-up menu. For more information, see Setting Up NetBoot Service.

   To save the image somewhere else, choose a location from the Where pop-up menu or click the triangle next to the Save As field and navigate to a folder.

10. Click Save and authenticate if prompted.
