I can get the /proc/cpuinfo tomorrow, but I figured > the dmidecode stepping info was accurate. Is it not reliable? DMI is useful to get the BIOS version string, not much else. Here you want the output from the CPUID instruction, which is displayed as family/model/stepping in /proc/cpuinfo thanks, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
