For what it's worth, my IBM ThinkPad (model i1500) runs a Celeron @ 366 MHz. Here is what /proc/cpuinfo reveals: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 6 model name : Celeron (Mendocino) stepping : 10 cpu MHz : 365.820 cache size : 128 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr bogomips : 729.08 Notice that the MHz is correct. But your model 600 is olde rhtan mine, so Tom may be right about your being underclocked. -- Dave Sherman <[EMAIL PROTECTED]> Business Solutions Group, LLC
