[Roo] seems to think we’ve been neglecting the NSLU2 or “slug”. It’s true we have spent a lot of time fawning over the Linksys WRT54G instead. The slug is definitely worthy of attention though. It is a small network appliance with two USB ports that you are supposed to attach disk drives to for simple network storage. Add a little custom firmware and you’re free to use the USB ports for whatever you want.
The XScale processor in the slug comes underclocked from the factory. Following the instructions on the NSLU2-Linux wiki you can pop one resistor off of the circuit board to restore the full 266Mhz. Benchmarks, temperature, and power consumption after the change are covered.
