I recently put an IDE hard drive in one of the free optical drive spaces in my mac pro. I reformated it so the os x could read and write to it. I still cannot install applications to it since it is not the start up disk. I also cannot partition it with boot camp so i can use it for windows. I looked in the start up disk pane but i cannot figure out how to set it so i can create a windows partition with boot camp on the IDE drive. Any help with this would be awsome.

That's unusual. Most applications install with a simple drag-and-drop and can be placed anywhere on any partition or drive. Even apps that install to the /Applications directory can typically be moved elsewhere if you so choose. Only Apple's apps "need" to be in the /Applications directory (for the Software Update mechanism to work properly).

Do you get some sort of error saying you can't "install" apps to it (install is in quotes because, as Brad says, installing is often just drag and dropping)? There are some things like printer drivers or databases that need to be on the root drive but I can't think of more than a handful of these.

When open up a dmg to install and it shows the hard drive options there is a red exclamation point over the ide drive and the only acceptable drive is the original SATA drive that came with the computer.
