In this step we're going to learn how to use Apple's System Image Utility
to build a NetBoot Installer. This process can be used with any or a combination of Installer files.
Note that if you're serving to both PPC and Intel Macs, you'll need to build seperate Images unless the Install file you're using is already a Universal Installer. Also, if you wish to boot the Installer from an Intel Mac, the BootImage must be created on an Intel Mac or from OS X 10.5 or later. This is because the necessary pieces aren't available on a standard PPC install of OS X 10.4.
Here, I'm going to demonstrate creating an Installer for the most recent PPC Combo Updater. I will make notations on what to change for the Intel (i386) variant. We're going to ignore (even override!) the more complex functions of the utility. You're welcome to experiment with those features later. Feel free to post your discoveries!
Since you've rebooted (you did catch that in the last step... Right?), log out and back in as the Root User.
Download the most recent Combo Updater from Apple's website. In this case, it will be the OS X 10.4.10 Combo Updater (PPC)
. Note that this comes as a disk image file. Double-click it to mount it.
Launch the System Image Utility
and note that the New Installer
icon is already selected (picture 1
). Enter a title for the Installer and give it a unique number under 4096 (I start with 1024). You can give more details in the description. Leave the NFS
Click the Contents
tab and set the Image Source pop-up menu to Custom Package Install
, the Default Language to <Your Language Here> and finally click the Plus
button to locate and select your Installer image from the mounted image (picture 2
Optionally, you can go to the Installation Options
tab and set Enable automated installation
to allow the Macs booted from this image to operate without user intervention (picture 3
). This is handy if you have a number of Macs on the same network that need the same update. Personally, I leave it off.
Click the Create button and agree to the license (pictures 4 & 5
). You will be asked where to save the NetBoot Image (picture 6
). Notice the pop-up menu toward the bottom that reads Serve from NetBoot sharepoint on:
, select your hard drive from here. This indicates to you that you did, in fact, setup the Sharepoints correctly! Give the image a name without spaces, like Install_10.4.10
and click the Save
Wait until it's done... (Go get a coffee, tea lemonade... what-have-you...)
You can now quit the System Image Utility.
