IOReg file is not reflecting the changes made from the Config file. You either booting from a different source or you need to select 'Reset NVRam' during boot to update the changes. There's no HDAU for Skylake system and up. At OC boot screen, if you don't see the option, then press spacebar. That should show the Reset NVRam option. Select that, it'll go through a quick reboot. Then boot regularly. Is the current display connected via HDMI or DP?

I'm using Sinetek-rtsx v2.2, have not tested Sinetek-rtsx 2.3 yet. Maybe try downgrade and see if that makes a difference. I have no issue on my E7270 with sleep/wake.

Don't seem to be able to find 'CFG Lock' in your BIOS. Might not exist in older systems. I do see DVMT offset if you need to modify that. 3421_IFR.txt.zip

@dave.stl Give this a try. Successfully tested to boot from USB installer Big Sur Beta 2. Config include settings for DW1820a, if you don't have that device, make sure to comment it out. It'll be wise not to upgrade or install over your Catalina as Hervé advised. Either get an external drive or replace with a spare M.2 drive if you want to test Big Sur E7470_OC.zip Update to latest OC release and kexts E7470_OC_0.6.2.zip

post debug file, leave out themes folder if files are too big Before compress and attaching the file, verify there's an IOReg file, not just IOReg.txt file If missing, go to applications folder and run IORegistryExplorer.app Save and add it to the debug folder, compress and attach it here for further assistance

@davidfrei7as RealtekRTL8111.kext is not found in kexts/Other Where did you put it? If it still doesn't work after you add the kext I attach early, you might want to downgrade Clover v5120 to V5119 Some known issue with it

You can update Sinetek-rtsx with that latest https://github.com/cholonam/Sinetek-rtsx/releases/ Where in the Clover Config file did you reverse the PS2 command and alt key? You can reverse it in Keyboard preference / Modifier Keys or you can modified the info.plist in VoodooPS2Controller/Contents/Plugins/VoodooPS2Keyboard Under IOKitPersonalities/ApplePS2Keyboard/Default/Swap Command and Option to No or Yes

Oops, forgot to add the AppleALC to the kexts section of Config Also remove the memory change config.plist.zip

What's the issue when you plug in the network cable? Do you get an IP address? Is it detecting a network cable? Please explain...

@davidfrei7as That kext is vanilla so it's fine. Check your BIOS, make sure Ethernet is enabled.

Try this. Replace Config file. Add SSDT to ACPI Add AppleALC to kexts folder and remove VoodooHDA 3070_HDMIaudio.zip

attach the ROM file

/L/E = Library/Extensions /S/L/E = System/Library/Extensions You could check by running this command from the terminal sudo kextcache -i / Whatever listed in the outlook are 3rd party kexts that are added

Use hackintool.app. Click on the sound tab to verify

Correct. This would be the best kext for it As I mentioned earlier, make sure you don't have other versions anywhere else RealtekRTL8111.kext.zip

post the device VEN/PROD ID Make sure you don't have both version running at the same thing Check if you have it in /L/E or /S/L/E

OpenCore?? Here, replace the Config and add the ssdt to ACPI folder. Make sure to select reset NVRam 1st otherwise the setting won't update. E5450_OC_Audio.zip

Place a check mark next to Custom and change the value to a different value than 64k (I suggest the last one) Now you should be able to Read and Backup

Nope, wifi not supported As for Realtek Ethernet, since you didn't mention the complete model VEN/Prod ID, I could only advise you to try one of these RealtekRTL8100.kext RealtekRTL8111.kext

Use the Universal Backup toolkit from this guide to extract the ROM file. You might get a warning from Windows

@davidfrei7as If you have an Intel Wifi, give this a try, no guarantee. Add kext to kexts/Other and use the app to connect. As for ethernet, is it also an Intel or something else? If it's an Intel, use Intelmausi.kext IntelWifi.zip

attach the ROM file you have extracted from your system

It's really simple. Go to BIOS, select Load Default, Apply and reboot. Go back to BIOS again and set to the following: UEFI enable AHCI enabled Secure Boot disabled

So what's not working? Trackpad: use Alps touchpad kext by Dr. Hurt. You can find it in R&D section Wifi: What does it have? Intel is not supported. Look in R&D section for list of supported devices Audio: Make sure you have latest Lilu.kext & AppleALC.kext and set layout-id to 11 Battery status: Make sure you have SMCBatterymanager.kext if you're using VirtualSMC or ACPIBatteryManager if you're using FakeSMC.kext Post debug file if you need further assistance. Can't help you blindly not knowing what you have

@MatiWaldi Give this a try. Replace Config and add SSDT to ACPI folder 7400_OC_I2C.zip
