I missed those in terms of virtualization, but it seems that all core2 support "intel 64" which I assume means emt64t, and what I thought Valdis meant by "the lower numbers are 32-bit-only chipsets." They all do seem to have 64bit, and should run 64bit Linux just fine. -- bill davidsen <davidsen@tmr.com> CTO TMR Associates, Inc Doing interesting things with small computers since 1979 - 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/
