Using Jim's example I would modify the his recommendation as follows:

On boot you will be presented with a menu offering you a choice of:

   Fedora Core (2.6.10-1.760_FC3)
   Fedora Core (2.6.10-1.741_FC3)
   Windows XP SP2

Windows XP SP2 is the default selection which will boot in 8 seconds
if no action is taken by the user.  This configuration lets you boot
an older kernal if you should encounter problems.
