Re: [CentOS] question on CPU
What's the status of ACPI? Is it enabled in the bios? Is the acpi service installed and running? I see nothing in the bios for ACPI which is odd. in /proc/acpi/processor there is a CPU0 and CPU1 the info file shows process id: 0 and 1 in each file. So it looks like its there but /proc/cpuinfo still only shows 1 entry. Just not sure the OS is really using two cores. It seems like its not. jerry ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
