This process was discovered researching how to Zen a Boot Camp partition. Those instructions can be found here.

One of the concerns when trying to deploy a Zen image is the HAL. Our base image has a standard single processor ACPI. However some of our new machines are dual-core, and as such need the ACPI updated. Corey Webb, our Zen guru, created an add-on image to swap out this ACPI to Multiprocessor. I stumbled across this when I was having an issue with an IBM T60 that wouldn’t wake from sleep. Thinking this might help our success with imaging the Intel Macs I applied the add-on and was met with great success.

Taking this one step further, I noticed that my Parallels VM of just a standard Windows XP install had a ‘Standard PC” HAL. I asked Corey to create an add-on image that would swap out the HAL with ‘Standard PC’. That’s it!

Just boot your VM off the zen imaging CD, pull down your base image and an add-on to replace the HAL. You’re done. Once you’re up and running you can send ctrl+alt+del to login from the VM menu in Parallels. After installing the Parallels Tools (an MSI that could be deployed to the maching via Zenworks) you can press (in this order, holding each one until they are all depressed) alt then ctrl then fn then delete.

This week we’ve discovered some additional noes about getting a Zen image onto (into?) a Boot Camp partition. The process is well documented but is rather time consuming. The 3 biggest parts are 1) swapping out the ACPI HAL from our base with a multi-core ACPI. 2) The boot.ini pointing to the 3rd partition on the Mac HD 3) Using the sync tool in rEFIt to sync the mbr after imaging.

Hopefully in the near future I’ll be able to test if pulling down an image directly is possible. (img rp $PROXYADDR //$PROXYADDR/baseimg.zmg a1:p3 + an add-on image with Multiprocessor ACPI is a hint)

Here’s a basic rundown:

From Start to Finish

1) Prepare the Intel Mac
a) Bootcamp, NetRestore, rEFIt

2) Prepare the add-on images:
a) Create an add-on image for XP drivers, correct boot.ini (partition 3) and correct muli-core ACPI

3) Prepare the Windows Disk Image
a) Install the Zen base and add-on images using the ZenWorks Imaging tools. Shutdown and boot into Target mode
b) Create an NTFS master disk image (base.ntfs) using NetRestore Helper

4) Restore the NTFS disk image to the Bootcamp partition

Future Deployment

Once you have a base NetRestore image, you can simply follow the following directions.

1. Install Bootcamp on the Mac meant for deployment.
2. Partition the HD as you like.
3. Restart into OSX and restore your base NetRestore image to the Boot Camp partition.
4. Install rEFIt and restart
5. Resync the MBR if needed and boot into Windows
6. Let sysprep run.

Additional Notes

You can’t use a Macbook as the main imaging machine. The keyboard does not work with the Zen imaging CD. Nor does an external keyboard. This limits you to an intel iMac, Mac Mini, or Mac Pro.

Once the XP drivers have been installed you can press the following key command for Ctrl+Alt+Delete.

Fn+ctrl+option (alt)+command (Apple)+delete

To right click, after the XP drivers are installed press the following key command:

Right command (Apple)+Trackpad button

I’m totally digging the new iTunes 7. Every release I geek out of ther changes Apple makes. I haven’t had a single bad experience upgrading to the next version. They just keep making the dang thing better. I like the new Coverflow interface, the super cool album art finder and the greatly improved iPod settings ‘panel’. But there are two things I’d like to mention that detract from such a robust program; the new UI elements, their darker than normal look and the huge memory usage. I’ve found fixes for the UI but have no fix for the memory usage. 🙁
Black is the new Aqua

I don’t care for the BIG BOLD LETTERS used for the header in the Source list. It’s rather distracting. Another issue with the source list is the amount of wasted space between the different groups. But hey! It looks like someone felt the same and posted this hint on macosxhints.com. No more BIG BOLD LETTERS!

What is up with the dark and dreary black and grey UI elements? Where’s the pretty aqua blue? Oh, ok so this is a ‘new’ version of iTunes, we get it. Yeah…So, Paul Barlow to the rescue with his great little Aqua4iTunes app. It replaces that dreary black and grey with nice shiny aqua buttons! Check out his great little beta here.

So far I’ve found fixes for the big things that bother me. Now let’s talk about something I can’t fix. The amount of memory iTunes uses when invoking the Coverflow view.
Feed me Seymour!

Below is a screenshot of iTunes at idle. At this point all I’ve done is open itunes and let it sit for a moment. I’m not playing a song, downloading anything, or updating my iPod. Just idle.

iTunes is using a very comfortable 34MB of ram, no biggie. Now lets turn on Coverflow.

I flipped through my albums for a few seconds and the memory usage increased to 563MB of ram. That’s 1/3 of my total memory dedicated to one single applicaion. Wow. I have a modest library, with about 8GB of music. Ok, so let’s turn off Coverflow and reclaim that memory…

Uhhh..Ok iTunes where’s the rest of that ram? 329 MB is still being used? How do I get that back? What if I close Coverflow, wanting to free up some resources to open another program? I have to close iTunes and reopen it. Groan.

These are minor compared to the other problems I’ve been hearing about. So I’ll chalk this up to a new version glitch/bug/rushtogetitoutthedoor problem. Here’s to hoping this memory monster will one day be tamed. I’ll just be glad I’m not running this on a G4 iMac with 245 MB of ram! Ouch.
