Laptop Specs -

Alienware m14x r2
I7- 3360qm
Intel HM77 chipset
500gb 7200rpm sata
32gb SSD
dvd/cd burner
nvidia gt650m 2gb
intel hd4000
2 usb 3.0 ports
1 usb 2.0 port


The issue im having is with installing Mountain Lion through a USB stick. Whenever it gets to the point of "No Interval found for. Using 8000000", the jump drive in the usb 2.0 port turns off and it starts repeating "waiting for root device". I have tried swapping ports to the 3.0 ports, but they do the same thing. It loads chameleon and starts to load the kexts, but it produces the "waiting for root device" everytime after the "interval found".

I have tried to create a Vanilla USB install using the guide from the forums, "#####", Myhack and all produce the same error. The only way I have gotten into the OSX Mountain Lion Installed is using "iatkosml2" and that was through a DVD DL. But when it starts to install at the 9 minute mark it brings up an error that says "Install could not be completed, please call your manufacturer".

I have also used majority of the boot parameters, -v -f -x GraphicsEnabler=No USBBusFix=Yes UseKernelCache=No. I Even found a boot parameter "rd=disk0s2" And that did not help either. None of these parameters let the Mountain Lion install load from the USB ports.

Is there any kexts or boot parameters someone knows that will help me get Mountain Lion installed on my M14X R2.

Also, I am in the process of creating an IMG from the USB stick. Hopefully to where I can burn it to a DVD and maybe install that way.


Spark Notes:

Tried Vanilla, #####, MyHack, = produce error "waiting for root device"
Iatkos = gets stuck on 9 minute mark of install
I think the reason why i cant install through usb is that once it loads the kexts, the usb port becomes disabled (maybe i need the right kext?)


Thanks guys, BTW i have searched and searched for the past 4 days to try and figure this out.

Ok guys.. Cross your fingers.. I tried to install with the DVD that was made from USB installer and it wouldn't work. I tried to get it to boot with ##### but that didn't work. So I tried to use the USB stick to load chameleon n then try the DVD. While in chameleon I hit F5.. And all of a sudden it started loading kexts... And it finally just loaded the installer through USB! I don't know how it loaded but it did. I will update u with progress

SUCCESS!!!!

So I reinstalled using 10.8.3. I created a USB installer as that was the only way I could get it to load. It installed without any issues. I install nullcpupowermanagment and fakesmc using kext utility. I installed voodoops2, voodoo battery, and voodoohda 2.8.2. I created a dsdt and patched it using the Alienware m14x patch from olarila.com. Also have full accel on hd4000, but the nvidia gt650m does not. I deleted the nvidia kexts as well to not cause conflicts. Wifi works using an airlink 101 USB wifi adapter.

Alienware m14x R2
I7-3630QM 2.4ghz
8gb ram
500gb hd - windows 7
32gb Samsung msata ssd- Osx 10.8.3
DVD/cd burner - working
Intel hd4000 - qe/ci full acceleration
Nvidia gt650m 2gb - not working
Creative recon3di - working with voodoohda 2.8.2
Internal hd webcam - working
Internal card reader - not working
USB 2.0 1 port - working
USB 3.0 ports - sometimes working
Trackpad/ keyboard- working with voodoops2
Battery indicator - working with voodoobattery

I extracted a dsdt and patched it eith a patch from olarila.

Everything works that I could care for. Startup and shutdown happen quickly no delays. It starts and is functional within like 30-40 seconds from push of start button. I'll post a video or screenshot later today

no problem man, let me know if you need any help. I realized i need to do a SSDT to enable full intelcpupowermanagement. As in osx, my laptop only gives about 3 hours of battery life, while in windows 7 i get about 4+ hours.

I'm interesting to buy m14x after haswell alienware release.
Has the battery life become more than 3 hours under OSX now?
And how many fingers can the trackpad work with?

Could you try to find if there is an option under Bios to disable Intel or Nvidia Graphic and post a screenshot here?

Really thinks! :)

I have an alienware m18x r2 with the same sound card and I am unable to get it working. I installed the voodoohda 2.8.2 kext as you mentioned but didnt worked. Do you have the kext that is working for you to send me?
