Thanks, Is there a guide somewhere on how to read the cpu info. I do remember seeing stuff about hyperthreading on this box. Does hyperthreading imply 64 bit. Here's the cpu from another box that has hyperthreading, but I was assuming it was not 64 bit. Can I run a 64-bit kernel on this one? processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 3.40GHz stepping : 5 cpu MHz : 3392.058 cache size : 2048 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 sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe up cid xtpr bogomips : 6789.18 On 5/21/07, Scott Silva <ssilva at sgvwater.com> wrote: > drew einhorn spake the following on 5/21/2007 9:45 AM: > > Once again there's stuff I understand and more stuff I really don't > > understand.
