Here, please answer a few questions: 1) What's your CPU option in kernel configuration file: I686_CPU or I386_CPU? I guess yours is I686_CPU. 2) What's the specific model of your CPU? AMD Duron or Athlon? What's the speed? With your these answers, I could write a small patch. If you're willing to try that, let's see how it goes. Cheers, Bin
