At the top of the file /etc/grub.conf (or menu.lst) there is a line which reads default=x

x is usually 0 and that means it boots as default the first operating system in the list (zero-indexed). To change the default boot option you just change this number, remembering they start at 0.
eg If WinXp was the 3rd OS listed you would change the line to read
default=2

GRUB is nicely configurable and 99% of what you will need to ever work with is in this file, once changes are made you just save and reboot.
