HD Install :: Proper partitioning?

I currently have this on my box
hda1 Boot Primary Linux ext3 [/boot] 105 MB
hda2 primary linux ext3 [/] 3997.49 MB
hda3 Primary Linux Swap 201.28 MB

WHat should I keep and what should I delete in order to load DSL on my box? What I have right now is COre 2 Fedora, and it is just slow and a hog, my box is way to slow and way to small in the memory department.
