Windows 98/XP Dual Boot

I have a PC currently running under Windows 98SE. I’d like to upgrade my OS to Windows XP however, some of its programs and applications may not run under XP environment and I’ve just heard of this dual boot feature of Windows XP which allow the user to choose between 2 OS upon start up. Can you give me the detailed procedures how to get this done? If there’s a need to partition the hard drive, can I use Partition Magic Utility? Thanks….
