Adding XP to boot loader menu

I plan to install Freespire 1.0.13 on a PATA drive while my XP drive is disconnected internally (a SATA drive). I'm doing this because I don't want Freespire to mess with the SATA drive at all. So I'm going to need to add XP as an option to the boot loader menu. How do I do this?

I'm not familiar with Freespire, but typically it is fairly easy to do. Most distributions use the GRUB bootloader to do this. Configuring GRUB is fairly simple with a little bit of reading, and Freespire just might have a utility to make it even easier. Either way though, it's an easy thing to do. The best thing to do would be to do the install like you have planned, then tackle that issue afterwards taking note of what bootloader you are using and the tools the distribution might have for you to add an entry in it.
