We recommend you create two images for your campus. One for your G3s and one for your G4s. For this process you will need the following equipment and supplies: 1. An eMac and white iBook to temporarily use as your Model Image Computers. 2. One Apple formatted FireWire Drive w/cable containing the district images and at least one bootable partition. (supplied)
Preparation	a. Set up your Model Image Computers with your software and settings just the way you want them. b. Make sure they are plugged into your campus network. c. Gather Installation disks and any required serial numbers for all the licensed software you plan to load onto your custom campus image. Note: Software that is not licensed for your entire campus should NOT be installed on the image. If you would like to use Apple Remote Desktop Administration to install SW and/or provide support to your campus computers, contact Steve Jeske for further information. Training for this SW application will be available. It is also advisable to keep these two computers as clean as possible for future use as Model Image Computers. By that we mean, don't install non district conforming software on them. Do not save user documents on their hard drives. As you find "glitches" in your image, fix it on the Model Image Computer and periodically create an updated campus image. Caution: Images larger than 2 GB in its compressed .dmg form cannot be installed using the HTTP image server technique we describe. However imaging with the use of a FW drive does not have this file size limit nor does using the afp:// protocol. Creating separate images for each grade level or dept. is possible but will greatly increase the complexity of this upgrade process and complicate later support of your computers.

Step 1 Boot the Mac	a. Plug the FW drive into the first Model Image Computer using the supplied FW cable. b. Boot this computer, while holding down the "Option" key. This allows you to select the drive and operating system from which to boot your computer. c. When the selection window appears, select the OS X Partition on the FW drive. Your Model Image computer will now boot from your FW drive.

Step 2 Install the District Image	a. Follow the "Imaging Your Macs Using NetRestore and a FireWire Drive" directions for imaging a computer. b. The Restore process will begin, reimage this Model Image Computer with the district image, verify the restored image and reboot the Model Image Computer. IMPORTANT NOTE: When modifying the district image, DO NOT move or rename system files that Apple's OS Install CDs have placed on your hard drive. Some of these are placed in the System folders and some in the Application and Utilities Folders. The reason for this has to do with SW Updates down the road. The next SW Update you run may only install parts of files and or folders if it cannot find the original because it has been renamed or moved. This may cause irradic operation and/or crashes and make your custom image unstable. In addition, we discourage the installation of third party system modification software. Neither Apple nor AISD Desktop Support will guarantee that this image or any Apple SW Update will function properly with any third party modifications to the system software files.

Step 3 Install Campus SW Modify Teacher User Account	Before making any modifications to the district image, be sure to read the IMPORTANT NOTES above. a. Following reboot of the Model Image Computer you may be asked to log into the Model Image Computer. Log-in as "Teacher." See your training notes for teacher password. b. Install additional teacher applications and student applications that should be on your campuss image. c. Launch these applications and test them for compatibility with the district image. d. Once you are comfortable with their stability and compatability, add their application icon to the teacher's Dock. e. Log in to your campus server. Create an alias of the icon for this server that appears on your Teacher user's desktop. Label this alias appropriately. Add any other aliases for your teachers as appropriate. f. Launch Internet Explorer and add any Favorites (Bookmarks) as appropriate for your campus. g. Log out of the Teacher user account.

Step 4 Modify Student User Account	a. Log-in as "Student" and leave the password blank. There is no password for the Student user account. b. Repeat the process of adding applications buttons to the Student user dock, Server and other aliases, and any additional IE Favorites (Bookmarks).

Step 5 Test Custom Image Document Campus Modifications	a. When finished with these modifications, reboot the Model Image Computer and test all of your changes. Make modifications as needed. b. Record your campus modifications on the Software Specifications Document located in the Users/Shared/ directory. This document is meant to reside in the Users/Shared/ directory with an Alias to it located on the Teacher user's desktop to inform teachers of the SW and other features on their computer.

Step 6 Create your dmg image	a. See CCC Settings & Instructions.

Step 7 Move your custom image to the FW drive	a. Locate the new customized image you just created. It will be located in the root directory of one of your FW drive partitions. Drag this file to the Installs folder in your OS X partition or other suitable location. b. TRICKY PART: You will get the message that this file is owned by Root and you do not have enough access privilages to complete this operation. Not to worry. 1. Click once on your custom dmg image to select it. 2. Go to File/Get Info. 3. Click to open the Ownership & Permissions window. 4. Click the padlock and enter the Teacher user's password. 5. Click in the Owner window and select.Teacher(me). This should give you rights to move this file. c. Now try dragging this file to the Installs folder in this same partition if you were not successful before. d. Rename this image file using a unique name denoting when it was created and which image it is. Be sure to include the dmg extension. Example: cook_iMac_build_12.15.03.dmg WARNING: Use no special characters or spaces in the name of this file.

Step 8	Repeat this whole process for your your G4 custom image.
