Just spotted this one @ Theinquirer.net. Now all I need is a Intel Pentium 4 to test the utility out. All donations welcome. Hehe...

We had a small beer with Andreas Stiller from c't magazine in Germany and he told us all about a little utility he's written for the Pentium 4.

The utility will switch on and off some Pentium 4 configuration flags such as prefetch, fast strings and the like, so you can maybe play with the software and see how it works. Download Intel Pentium 4 Utility @ TheInquirer.net
