Am I right that is chipset on mainboard, who is saying - "I know....", not CPU itself? Is it better to switch off HT support in BIOS? Is it possible to generate CPU name as: "Pentium D 930" in /proc/cpuinfo? On the other server I have some 2GHz HT Xeons which can't be identified on Intel site because of strange naming pattern. I tried to find any utility for Linux to solve this, but it looks like everybody are using /pros/cpuinfo, which is not enough :) Regards, Eugene. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
