If I remember correctly all you have to do is scratch the sealant crap from in-between the bridges with a needle, exacto knife, or something similar. I would do some research though before you take my word for gospel. Sorry I didnt respond sooner, I have been inactive for quite a while now.

If you want to use your other CPU you do not necessarily have to buy an XP unlocking kit. All you need to do is fill in the gaps with super glue, and buy some conductive paint to paint the bridges. Rear-window defogger paint, which can be found at most auto-parts stores, works well.

With best regards,

You can't use a pencil trick with Duron 1.6 because Duron 1.6 is based on T-Bred and Barton processor modules. This means new 1.6 durons are super locked like new desktop Bartons.

You'll have to use the default 12 x multiplier on 1.6 Duron.

The only Athlon XP CPUs guaranteed to be unlocked these days are the 2100+ Thoroughbred B (not A, not Palomino) and any mobile Barton CPU.
