You will need an AMD unlocking kit. Most online comp. specialty stores have it now.
You put superglue in the lazer holes. Making sure not to get any on the contacts. Let it dry, then connect the contacts with conductive silver grease and its unlocked.
I noticed one place was selling a tape with silver contacts that you just lay right over the spot. Looked pretty trick. Don't remember the site though.
The kit should come with the Glue, Silver grease, cleaner, needle, and a magnifinder.

OR

An nForce 2 motherboard will automatically unlock it.

Here's the trace tape. Its 24.99 though. About twice as much as you can get a silver grease unlocking kit. This doesn't void the warrantee as far as I can tell, and looks a little more on the permanent(won't wipe off on accident).
