Hi Gentlemen,
Recently I have problem netboot new iMac. They seems to ignore the netboot server but my old iMac stills works. I was told I need to update the NetBoot Image so it can recognise the lastest hardware. I am not quite sure what to do at this stage. Can someone point me a direction or any other suggestion?
Thanks.

Take the newest Mac you have and set it up to how you'd like your NetBoot image to be. Then boot it in target disk mode and connect it to another Mac. On the Mac your "netboot" Mac is connected to, use the System Imaging Utility (included in the Server Admin tools) to create the NetBoot image of it.

    Hi Jared,
    Thanks for pointing out. I think I am on the right track. Just created a minimal OS Lion image and copied to NetBoot server to use as a source.
    There is the KB article
    https://jamfnation.jamfsoftware.com/article.html?id=64
    and also an Instruction in Resource Kit/All Tools/Casper NetBoot Automator.
    I am a bit confused here because I don't know the difference and which one to follow.

    Typically you'd use the Automator action as this is the newest way, and JAMF no longer supports the Casper NetInstall Creator after 10.6. However, what I do is copy casper imaging over, and create a loginhook to point to it, so that it's the first thing that shows up when someone netboots. Then I create the NBI file from that hard drive.

    Thanks. Today I just updated the nbi image, and it didn't fix my new Mac NetBoot problem. Don't know what should I do next.

    It's not something simple that's been overlooked like scoping that boot image to particular Macs is it? (either via model or MAC address, for instance)

    Do u mean the scope on NetBoot server or in Casper? I don't remember had such settings and plus it worked occasionally and when I reimage it again next day, it stopped working.
