[HOWTO] ACPI CPU Throttle Kext -Fixed

Hey guys,

I have managed to compile ACPI CPU Throttle kext to work with OSX 10.4.9/ netkas' kernel .Bear in mind it needs Netkas' Kernel , it does not work with with 8.8.1. I have edited few things to work with OSX 10.4.9

It might not work with first few tries , you might have to keep on loading it. If it gives you a problem , please tell me the problem {output} as i can debug it and improve it


This is from the OSX 10.4.4 era kext , fixed few things {although i got lots of things to fix} and released for you guys @ hackint0sh


Okay , enough of talking..now lets get to the work shall we

1. Unzip it to your root of the drive {or anywhere if you like ..but if you're a n00b/newbie..Then just put in this in the root of your drive

2. Fire up Terminal and type

Code:

---

sudo chmod -R 755 /ACPICPUThrottle.kext

---

Then type

Code:

---

sudo chown -R root:wheel /ACPICPUThrottle.kext

---

Finally , make sure you have the 8.9.1 with SpeedStep-Enabled kernel and fire up this

Code:

---

sudo kextload /ACPICPUThrottle.kext

---

Do a few times , it might rant that it can't find some ACPI headers..Just keep on trying until it says 'Hey..I'm okay...and we're good to go'

Next up can sysctl and look for new frequency settings. To change it , you can do it manually and/or use CPUThrottler2Beta2 [Google for it , I'll upload this later]

Once this is done , I'll upload a complete automated installer for you guys

UPDATE : Fixed some bugs and now its Officially 1.03. Just some minor changes on AMD K8 Power management , thats all

After type this one:

Code:

---

sudo kextload /ACPICPUThrottle.kext

---

I got this one:

Code:

---

kextload: kmod_control/start failed for com.OSx86Project.kext.ACPICPUThrottle; destroying kmod
kextload: a link/load error occured for kernel extension /ACPICPUThrottle.kext
load failed for extension /ACPICPUThrottle.kext
 (run kextload with -t for diagnostic output)

---

What should I do?
Thanks in advanced!

works fine except when i exit CPUTHROTTLE2 the settings are unloaded? how do i change it forever or manually do it thanx

Mmmm this seems sweet.. to bad that the only system I have that needs speedstep is SSE2 and it runs 8.9.1 netkas,semthex,oui:O.o/back to USSR_I3 kernel...

My question is: Any info on 10.4.9 SSE2 speedstep kernel now when 8.9.1 is open source?

hanibal : your bios does not support it. I will post a debugging output

I will be uploading a Dynamic SpeedStep version fixed. So that means , it will adjust the frequency automatically for you

Thanks prasys for your hard work!
below is my system:

Gigabyte GA-8IK1100 (875P - ICH5R)+Realtek AC'97 ALC658 (5.1) (2.0 Stereo works only)+Creative Audigy 2 ZS (Not working!)+Intel 3.0G, 800Hz, SSE3, HPET & non NX+Kingston 2 X 512 (1GB) DDRAM 400Hz+ATI X850 XTPE 256MB (QE, Q2D & CI Supported - AGPGart 2.2 Failed)+Maxtor 120G SATA (SATA Raid Function must be disabled in BIOS)+Pioneer DVR-111DBK (DVD-R) (Works Perfectly!)+LG DVD Combo (Works Perfectly!)+Intel Pro 10/100 VE (Auto Detected)

So, without ACPI CPU Throttle Kext, is it okie?

I think i got many system to work after fixing some bugs on it :D

#appleacpi @ irc.osx86.hu :D

I will release the complete installer later
