All works for mine. Thank you again.

Hi,Jack I've gotten well display by flashing bios back to version A12 and using the patched dsdt file extracting from A13. When I restart the computer, I find that Optimus option ,which will lost when patched A12 dsdt file is used, is still there. The only shortcoming is that it makes clover boot more slowly than usual. There is only soundcard that does not work. Can I use the kext from your Extra Zip file? I think I should patched the dsdt file at first. Could you show me layout id and sample patch code? Thank you very much.

Hi Jake, It doesn't work. Is there any guide about how to patch the dsdt for e6430? I think there maybe some difference with our original dsdt files, and I want to diy but I need to know what what did you do on your dsdt file. Thanks.

E6430 BIOS A13 | i5-3230M 2.6 GHz | 12GB DDR3 | Intel HD 4000, 1366x768|nvs 5200M Following the guide of "Dell Latitude E6430/E6530 with Optimus Enabled" https://osxlatitude.com/index.php?/topic/7268-dell-latitude-e6430e6530-with-optimus-enabled/ Using Clover+UEFI to boot Maverick. When login to the os system, there is weird graphical glitches on my screen. Is there a possible way to make me out? Thanks.

Yes, I see it. I am trying to turn my chameleon boot into clover boot following your guide.

Thanks for your help. I'll spend some time to study what you did to DSDT and SSDT files by comparing the difference and find out why to do so.

Here are dsdt files from bios using clover. Would you like give me any suggestion how to fix it? Thanks. origin.zip

Here are the attachments. There are three log files in bootLog.zip : 1. Successfully boot kernel log file without turning off nv card in dsdt. 2. Boot kernel log file with turning off nv card in dsdt and without enabling optimus in bios. Running into a black blank screen. No screen output. 3. Boot panic photo shot with turning off nv card in dsdt and with enabling optimus in bios. Thanks a lot. bootLog.zip Extra.zip

Here is my edited dsdt file. I added a PINI method which calls \_SB.PCI0.PEG0.VID._OFF(). Then I added this method to both begin of Method (_WAK, 1, Serialized) and begin of Method (_INI, 0, NotSerialized). The test result is following: 1.The optimus option is disabled: The boot screen with -v option will run into a black blank screen while the disk is still reading. It seems that nv card is really ignored by dsdt and the intel hd4000 video card is not recognized. 2.The optimus option is enabled: The boot screen with -v option will run into a panic screen where it says the intel cpu driver gets error in loading. dsdt_nonv.aml.zip

I didn't find the method of "_INI" but "_WAK", so I add "_OFF" at the start of method "_WAK" to disable nvs card. Then I restarted with arguments "-f" and I read the log gotten by command "dmseg". I found that the nvs card was detected by osx and the driver of it was loaded. The battery status icon at the top of status bar also disappeared.

How did you edit your dsdt file? I found the method of "_ON","_OFF" under "Scope (\_SB.PCI0.PEG0.VID)" in file "SSDT-7.aml". I also found the method who call them are "_PS0" and "_PS3" at the same place. I suggest that I should copy these method to node of "Scope (_SB.PCI0.PEG0.VID)" in file "DSDT.aml", then add calling of "_PS0" and "_PS3" to "Method (_WAK, 1, Serialized)" and "Method (_INI, 0, NotSerialized)". Is it a possible way out? I'll try it when I have some time.

My spec: Latitude E6430, BIOS A12 | i5-3320M 2.6GHz | 4GB DDR3 | nVidia NVS 5200M 1024 MB | Rebranded Dell DW1510 | Mavericks 10.9.1 I used the Extra-folder provided by Jake Lo to make it work except sleeping. Everytime the laptop went to sleep, I couldn't wake it up by pressing the keyboard and mouse. The only way to make it work is to pressing the power button to restart my computer. Is there any solution for my problem? Thanks a lot.
