How to install Windows 7 on extra Internal Disk

Apple's latest "Boot Camp Installation & Setup Guide" does not provide clear instructions to accomplish what I believe to be possible. A review of this forum for past articles provides more clues, but still leaves me wondering what are the actual steps to achieve my goal:

Install Windows 7 on my MacPro on an internal disk that is not in the first hard drive bay. I want to make the Windows disk it's own single partition, and keep my MacOS on it's own drive as it currently exists.

Here's what Apple's latest guide states:

"If you have a MacPro with more than one internal disk and you want to install Boot Camp on a disk that isn't in the first hard drive bay, remove the drives in the lower numbered bays. You can reinstall the drives after you install Boot Camp."

I have a call in to Apple Support and it was immediately bumped up to Engineering because none whom I spoke with were able to answer the question. In fact, they told me that no one had ever asked the question before!

So I would like to understand the actual steps. Could I boot from the Windows CD and choose the internal disk I want to install it? Do I need Boot Camp to load and install the Apple supplied Windows drivers?

MacPro 2.66 GHz Quad-Core Xeon, 8 GB 1066 MHz DDR3, 3 internal drives. OS X 10.9.4
