The Mini is an Intel Mac - Macmini2,1 (A1176) Core 2 Duo, 2GHz. It's currently running 10.6.8 on the Mac side and XP SP3 on the Windows side. The Tiger disks (2) are the gray-faced Apple logo disks; the Leopard upgrade disk is the black/purple OS X disk. And you are correct, I DO NOT need/want/plan to make any changes to this system.
I now have the iMac, set up from the Refurb store with Mountain Lion. This is my first contact with ML, only had the machine for a week, so strictly from an OS X standpoint, I don't know enough yet to decide whether ML is better/worse than Snow Leopard (or Tiger, which I still run on a 9-year-old Power Mac).
What I WANT to do is set up the iMac to run Windows as well. As I understand it, I can:
use Boot Camp and and run with Windows. The iMac has Boot Camp 5.0.0 which, according to what I've read at the Apple support pages, will not allow me to install XP; I have to run with Win 7. This is what Apple says. To do this with my older XP software I have to use the 64-bit Pro version to run in XP mode; this is the version of Win 7 that I have, I just don't know ANYTHING about Win 7 to know how this will work compared to just running XP natively.
I can use Parallels 8 which, supposedly, will allow me to run XP or Win 7; if I do this, I could stick with XP and not worry about learning anything about Win 7. On this approach, I have no experience with Parallels so I have no feel for running Windows in virtual mode versus running it natively with Boot Camp.
These are the basic premises that I started with when began this discussion the other day. Logically, it seems like running in Boot Camp should be a more efficient way to operate versus the virtual machine; the advantage of Parallels seems to be the time saved in switching back-and-forth, along with better use of the hard drive space by not having to allocate a specific Boot Camp sector.
When I talked to the Apple rep last night, I gave him model and serial number; he said that a 10.6.7 restore disk does not exist in their system. FWIW, I talked with a tech rep the day I received the iMac because I had a question on a different subject. He told me that, based on the serial number, this machine was originally set up with Lion when it was "new".
I did read the link that you sent regarding setting up XP using the Win 7 disk. Sounds interesting, guess it's something that I could try if I really want.
I don't NEED to set up the iMac to boot with Snow Leopard. That was your suggestion as a method to run Boot Camp with XP instead of converting to Win 7. As stated earlier, I haven't worked with Mountain Lion long enough to compare it to Snow Leopard.
Hope this clears things up.
