After days of searching and failing on different ideas on how to get boot camp to work with OS Xs' SW RAID, I finally did it. This is how I did it and I've read other ways to do it, but this is the only one that worked for me. Just thought I would share for anyone who was interested. After I got my Mac Pro, I instantly used up all 4 SATA slots to setup RAID 0 through the Disk Utility application. I was bummed to find out that I couldn't boot camp in this configuration, so off to the internet I went. First I took all 4 drives out of my Mac Pro and inserted a new drive that was not a part of the RAID into slot 1. I booted my machine with the OS X install disk in it, erased the hard drive, and installed OS X. Nice, fresh install. I then boot camped the machine like you would in any other normal circumstance. I powered down the Mac and took out the HD from slot 1. I placed the hard drive into the extra optical bay and hooked it up using that free SATA cord. If your thinking why didn't I just use this SATA slot in the first place, I did already try that. The Windows installer didn't like the fact that it was in that location for some reason, so I had to restart the entire process again after switching the HD to slot 1. I would think that you could also set up this HD as an external hard drive at this point, but I'm not sure. I just used the empty optical bay. After placing the HD in the optical bay, I put back my 4 HDs into their original positions. Restarted the Mac and held down the option key. Unfortunately you will have 2 installs of OS X on you machine, but to me that didn't matter. As long as I had an option to boot into Windows. You only lose about 20 gigs on the HD you boot camped. And that was that. Spent days looking for a workaround and finally got it. Sharing this for those that are interested, but perform at your own risk.
