I am having difficulty installing xp on a second drive I have put in my mac pro. I understand that the documentation indicates there should be no issues with installing xp on a second drive, but it also states that "Windows XP requires its own partition on your computer's internal startup disk. Boot Camp Assistant creates a second partition on your startup disk..." My question is this - do I need to move the second drive into the primary drive slot in the Mac Pro? If so, how do I get the system to recognize that drive as the internal startup disk? Will this affect my drive that has OS X installed on it? I'm not sure how BootCamp handles these issues, but currently it will not recognize the second drive as a drive onto which it can install XP. I have used BootCamp to create a single windows partition on that drive, and it still does not recognize it. Any input you could give would be very appreciated.
