mLine 32:
Line 32: − − ==Using CPUspeed== − − Your MacMini supports multiple cpu frequencies. Using multiple frequencies can even reduce power consumption but without reducing your cpu power. The used frequence depends on the demanded processes. Login at the Serverconsole and look to youre actual used cpu frequence − # cat /proc/cpuinfo − − # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver − This shows 'centrino', which means that your MacMini would use the centrino driver. − − You can see the possible cpu frequencies with the command − # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_availaible_frequencies − My MacMini shows the following frequencies: − # 1833000 1667000 1500000 1333000 1000000 − Using multiple cpu frequencies, you have to config your system as follows: − # vi /etc/cpuspeed.conf − Edit the file /etc/cpuspeed.conf and uncomment the line with the driver − # DRIVER="centrino" − Save this file with the ':wq' command − − Edit the file /etc/lilo.conf − # vi /etc/lilo.conf − Add the append command after the 'linear' line − # append="apm=off acpi=on" − Save this file with the ':wq' command − # lilo − Last but not least config the servive db so that the cpuspeed service starts when booting your MacMini: − # db configuration setprop cpuspeed status enabled − Save the whole configuration and restart your server − # signal-event post-upgrade − # signal-event reboot − From now on your MacMini should use successful the cpuspeed service to swich between multiple cpu frequencies. To control your steps, login to your serverconsole and type − # /cat/proc/cpuinfo − Now your server should use the min cpu frequence (Success).

Reboot your MacMini and finish your installation with the initial configuration. The standard lilo bootloader starts your server as usual.
