wern Posted January 2, 2015 Share Posted January 2, 2015 I made a fresh install with your files, but no HDMI-Audio, no internal display, the battery symbol shows me a x, i think there are a few hardware differences to your E6520 Tested with optimus disabled Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 6, 2015 Moderators Share Posted January 6, 2015 @wern, My mistake, HDMI audio is not working for E6520/E6420 with nvs4200m. It's working on my E6530 with nvs5200m. I'll continue tweaking to see if I could get it to work. As for the internal display issue, try this DSDT. I had fix the internal display and the battery issue.

wern Posted January 7, 2015 Share Posted January 7, 2015 You've added the nvidia stuff to IGPU, that makes no sense This HDMI codec has 3 devices DP1 and DP2 on dock, the hdmi device on the laptop is the last which is not working, only DP2 (which is the 1st) on dock is working Link to comment Share on other sites More sharing options...

VNMan Posted January 12, 2015 Share Posted January 12, 2015 Would like to post my experiences so far with my E6420. First the specs - BIOS A21 I5 2540M NVS4200M 4GB RAM 1TB HD - GPT, Windows 8.1 installed (400GB). Optimus Enabled. Well I followed this guide https://osxlatitude.com/index.php?/topic/7478-dell-latitude-yosemite-install-guide/ and OSX Yosemite installed on the free space of the HD. Have to set disabled NVidia in boot.plist for the screen to come up OK, if not I have corrupted screen. Audio is Grey out, after logon "Bluetooth Assistance" comes up (no keyboard found) although keyboard is working. Wireless card is on the way from China, so I cannot say if the wireless is working. Anyway, I have Windows 8.1 on this machine so I though I try Clover for dual booting with this guide https://osxlatitude.com/index.php?/topic/6935-guide-e6420-os-x-yosemite-10100-finalgm-3pb-4/ and guess what? OSX failed with KP and the culprit is AppleIntelCPUPowerManagement. Windows boot fine no problem, actually it booted faster than before. If I set UEFI boot in BIOS Windows boot OK, but OSX boot not working all I got is blank screen. If BIOS is Legacy, Windows still boot OK. OSX came up with "Refusing new kext com.apple.driver.AppleIntelCPUPowerManagement (v196.0) Already Prelinked (v128.0)" and got KP afterwards. The same happens if I boot with "Nocaches", this time no message about "Refusing" but still failed with "No HPETs!" and the culprit is AppleIntelCPU kext. And the strange thing is that Clover report boot args - j! ij! mnne!... Tried Clover 2k3133, 2k2999, 2k2985 same results. Anyway, with this setup I can only use Chameleon boot from USB and not clover. Help on getting Clover working properly so that I can boot from HD.

Administrators Bronxteck Posted January 12, 2015 Administrators Share Posted January 12, 2015 select asusfix and fixHPET using clover configurator or in clover GUI. Link to comment Share on other sites More sharing options...
VNMan Posted January 13, 2015 Share Posted January 13, 2015 fixHPET is [+] in Clover GUI all the time. Clover generated DSDT is used and still KP with HPETs. Will try with different Boot Pack and report back. Edit 1 - Got it to boot to OSX Yosemite 10.10.1, ran Hackintosh Vietnam Tool - "Fix AICPUM" and there is no more HPETs problem. Got sound with latest AplleHDA kext from Jake Lo. Cannot use NVS 4200M at the moment - Got some weird screen artifacts, purple stripes and low screen resolution. See that "display" reports 2 GPUs (NVIDIA and Intel). Tried to disable "Optimus" and OSX hang at "GEForce Started". Have to enabled "Optimus" and disable NViDia with "nv_disable=1" under boot options, then I only have HD3000 in "display" no QE/CI. Next steps - have to get NVS 4200M to work properly.

Moderators Jake Lo Posted January 16, 2015 Moderators Share Posted January 16, 2015 I made a fresh install with your files, but no HDMI-Audio, no internal display, the battery symbol shows me a x, i think there are a few hardware differences to your E6520 Tested with optimus disabled After a lot of trial and error, I finally got the NVS display working with the original DSDT. I guess Apple has made a lot of changes to their video kexts since 10.9.2 ( Nvidia and Intel). I went back and tested all the installer from 10.9.0 -> 10.9.5 and 10.10.1. That last version that the internal display shows up is 10.9.2. So I rolled back 10.9.5 installer nvidia files with 10.9.2 and it worked and also worked on 10.10.1. Files I replaced are: NVDAGF100Hal NVDAResman NVDAStartup (optional- works without roll back) So far I haven't see any issue, but will need further testing. Attached are the files if you don't have 10.9.2. Also included is an updated DSDT to fix the Battery issue and IOAHCISerialATAPI_Injector.kext to fix the DVD Player error.

wern Posted January 17, 2015 Share Posted January 17, 2015 The whole effort was not necessary, because with my patched dsdt the internal screen and hdmi-video is working with yosemite, but thanks anyway What i want to fix is hdmi-audio, for now it only works with voodoohda, which i don't want to use Link to comment Share on other sites More sharing options...
