hi! When i call "cat /proc/cpuinfo" on fedora core 3 (kernel 2.6.9) on my dell inspiron 5150 notebook it shows the following: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.06GHz stepping : 9 cpu MHz : 1595.024 cache size : 512 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 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr bogomips : 3154.27 When I call that command on the same machine in debian sarge (kernel 2.4.27), it shows this: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.06GHz stepping : 9 cpu MHz : 3056.552 cache size : 512 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 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 6094.84 Fedora recognizes the p4 mobile 3ghz as 1595.024 mhz and not as 3056.552 mhz as in debian??! How can that be? regards, oliver
