Concerned about outcome of additon of Windows

Hello, this is my first post on this forum. I have a normal MacBook, and today I installed Windows onto it. Following the Boot Camp instructions, I installed my OSX CD into the disk drive to install the Boot Camp features, but when the disk was read, it said that Windows Service Pack 2 was required in order to run the program. I could not find anything about that in the instructions, and I am confused as to what it is.

Also, without installing any of the Boot Camp features onto the Windows, is there anyway to access OSX upon turning on the computer? Any time that I turn it on now, it automatically goes to Windows.

Thanks

This is a double post, I answered it on the first one that came up in the list (the second post).

Yeah, sorry about that, I wanted to change the title and did not realize that I had already posted it.
