Updated, it didn't reboot.

Downloaded Update 5 from the download archive, and applied it in Control Panel. Everything is good so far.

XPEnoboot_DS3615xs_5.2-5967.1 can work.

[CPU Throttle Script Tutorial]

Change the script so it matches the available powersave governor.

Example:

/usr/local/etc/rc.d/S99Powersaving.sh

 

Script-content:

#!/bin/sh

 

echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu5/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu6/cpufreq/scaling_governor

echo powersave > /sys/devices/system/cpu/cpu7/cpufreq/scaling_governor

 

Make the script executable (look above this thread or "chmod a+x scriptname.sh"). Afterwards run it or reboot.

 

Thank you for this point.

I did some modification on the script. But seems it still doesn't work.

do if ! grep -q 'powersave' $c/cpufreq/scaling_governor ;

then echo powersave >$c/cpufreq/scaling_governor ;

done

 

Any suggestion?

Thanks.
