Thanks for tips. Tried it again a couple of times and got the same results. This is what worked for me; updated myhack to the most current version (3.3.1), followed the instructions per the link above but had to type dsdt=/extra/<dsdt filename> arch=i386 -f (all lower case), for it to boot the mlpostfactor usb. After that, the system began operating the way it was supposed to. Then to be bold, I decided to try to upgrade to 10.8.5, as I have a copy of the 10.8.5 app. It didn't work and reverted back to 10.8.4, but that's ok. I noticed in the picture in your original link that you have the speedstep meter showing in your menu bar. How were you able to get it to work? I tried doing a few different builds, but can't get it to show up.

Hello all, Long time lurker, first time poster. I'm usually able to find what I'm looking for with a good ole' search, but have been unable to in this particular instance. I am trying to install Mountain Lion 10.8.4 on a Dell D430 1.33ghz cpu 2 gigs of ram, and Intel graphics. I can initially install it successfully using the "extra" bundle only from this thread https://osxlatitude.com/index.php?/topic/2467-installing-ml-on-d430-gma950-with-full-qeci/. Then to get qeci, I create another usb and place the Mountain Lion app and postfactor in the applications folder of the current installation. After that, I create an "extra" folder in the usb and add the proper files from the original "extra" folder from the link. I then run postfactor and rebbot. At start up, chameleon is interuppted, I choose the usb and type in the following word for word: DSDT=/Extra/<dsdt filename> arch=i386 -f. It begins to boot then the screen dims and then goes black. Nothing else happens. I've also tried the following word for word: DSDT=/Extra/<dsdt table> arch=i386 -f, and it does the same thing. I've searched through the link to the other website, but it is 140 pages long, and I have not been able to find what I'm looking for. Any help that anyone can provide who has had success with this procedure would be greatly appreciated.
