==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. If you give Login at the commandServerconsole and look to youre actual used cpu frequence
# cat /proc/cpuinfo
you can see the actual used cpu frequence.
The command
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
ansers with This shows 'centrino', which means that your MacMini would use the centrino driver. 
You can see th possible cpu frequencies with the command
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_availaible_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"
and save Save this file.with the ':wq' command Edit the file /etc/lilo.conf and add # vi /etc/lilo.confAdd the append command (after the 'linear' line)
# append="apm=off acpi=on"
save Save this file with the file and type':wq' command
# lilo
Last but not least config the servive db so that the cpuspeed service starts when booting your MacMini:
# 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/cpuinfoNow your server should use the min cpu frequence (Success).
Have much fun with the energy efficient MacMini as your preferred SME home server platform !
