For this reason, it has become customary to refer to the Windows installation on a Mac as Boot Camp.

When "The Boot Camp Support Software" installs, the Windows partition is renamed BOOTCAMP. This software also provided a way to boot back to OSX and a utility to update Apple software such as iTunes. These drivers were part of a package referred to as "The Boot Camp Support Software". Once, Windows was up and running, better drivers could be installed to upgrade existing drivers and support other hardware such as the camera and sound. These newer DVDs contained the drivers need to allow Windows to install and boot on Macs. Instead, Microsoft released Windows XP DVDs with Service Packs already installed. Also, Microsoft installations allow for newer drivers to be introduced during the installation process, but this was never employed for Windows installations on Macs in 2009. When the difference is 8 years, this is difficult to do. Granted, to a certain extent, hardware can be designed to operate in a legacy mode in order to install an older operating system. Since Windows XP was released in 2001, one should not expect the DVD (or maybe CD) to contain the drivers for the 2009 Mac models. The Windows installation DVD needs recognize your Macs hardware in order to install the drivers needed to install and boot to Windows.

To install a particular version of Windows on a Mac, a few timing aspects need to be considered.

In fact, it is possible to run Windows on your Mac without any version of OS X installed. Therefore, the version of OS X currently installed has nothing to do with whether you can run Windows on your Mac. The firmware does not change when you upgrade to a new version of OS X. By 2009, Apple was shipping Macs with firmware or offered firmware upgrades that allowed Windows to be installed in BIOS/MBR mode. I will try to answer your question as best that I can.
