marlawre Posted June 29, 2014 Share Posted June 29, 2014 Hello all I am following this guide https://osxlatitude.com/index.php?/topic/2468-dell-latitude-d830-intel-gma-x3100-ml-with-full-qeci/ - I am working with ML 10.8.5. In the guide, I get to this step 6 under the ML Post Factor section: reboot off your initial ML disk/partition, interrupt the boot process at the Chameleon delay bar and select this newly created installer with options & flag: DSDT=/Extra/<dsdt filename> arch=i386 -f I enter this, it loads the white screen, and then the screen goes blank. I tried adding -v as well and it loads fine to the point I guess when it is loading the video drivers - that is when the screen goes blank. I have downloaded all the files from the guide, followed it step by step. Anyone else had this issue? Any ideas that I can follow?

marlawre Posted June 30, 2014 Author Share Posted June 30, 2014 Herve I select the USB stick to boot from (that is how I created the ML PF installer) and type: DSDT=/Extra/DSDT.aml arch=i386 -f Thanks Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 30, 2014 Administrators Share Posted June 30, 2014 Ok, nothing wrong there. The only thing I can think of is your screen resolution: you may have a model for which the DSDT provided in the bootpack is not adequate (it's the table for the 1280x800 LCD). The compatibility chart provides 2 boot packs: 1 for WXGA (1280x800) D830 and 1 for WUXGA (1920x1200) model. If you have the HiRes screen, just extract the DSDT from the HiRes pack and use it instead of the table you've used so far (replace the DSDT.aml file in /E/E).

marlawre Posted June 30, 2014 Author Share Posted June 30, 2014 I'm guessing it's safe to use the Lion HiRes pack as I don't see a ML pack on the compatibility page right? Thanks Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 30, 2014 Administrators Share Posted June 30, 2014 Don't use the Lion HiRes pack in full; extract the DSDT off it and place it in the ML pack from the guide, replacing the LoRes DSDT. If you have the HiRes screen of course, because you never answered... Link to comment Share on other sites More sharing options...
marlawre Posted June 30, 2014 Author Share Posted June 30, 2014 Sorry - I didn't get a chance to do until a little while ago - yes - it is the HiRes screen - I will put the HiRes DSDT into the Extra.. Thanks Link to comment Share on other sites More sharing options...
marlawre Posted July 1, 2014 Author Share Posted July 1, 2014 I have used the HiRes DSDT for MLPF and it works great. After running MLPF, the machine boots, but then I get the same black screen on the regular boot. I have copied the HiRes DSDT to the regular partition, and the machine will not boot - even with wireless disabled. I tried to put the HiRes DSDT with the lores bootpack and regenerate the MyHack installation - it won't install - just hangs after about 20 minutes...won't go any further and that is with wireless enabled and disabled - any ideas anyone?

Administrators Hervé Posted July 1, 2014 Administrators Share Posted July 1, 2014 You're using MLPF v0.3, not the older v0.2.2, right? Also can you check your LCD resolution in the BIOS info page? Link to comment Share on other sites More sharing options...
marlawre Posted July 1, 2014 Author Share Posted July 1, 2014 Yes - MLPF v0.3 and the resolution is 1920X1200. Link to comment Share on other sites More sharing options...
