You can make a partition in Windows XP. Go to start -> run -> diskmgmt.msc
I don't believe you will get a noticable performance increase with a partition on the same disk. It all depends on the disks mostly. If the game you are loading resides on DISK2 and the page file on DISK1 it will be faster than with both on same disk.
