Question imac 12.2
Hey everyone !
I have the following - Imac 12.2 with Intel Core i7 - 2600 / Radeon HD 6970M .
First of all I've installed Windows 10 (1909) from usb UEFI .
I've disabled internet connection for the moment of installing .
Then I've installed bootcamp drivers from USB.
It has installed Radeon HD 6970M driver version 220.127.116.110
Had no sound , used this guide from forum , loaded dsdt-modified.aml ( GUIDE DSDT override eGPU error 12 fix)
Now i have sound after reboot - Cirrus Logic cs4206B.
Also disabled applehfs.sys had VSS errors ( could not create restore points )
So if I enable internet connection Windows goes driver update and downloads driver and I get BSOD after that.
I've used wushowhide.diagcab to hide this - Advanced Micro Devices , Inc. Driver update for AMD Radeon HD 6900M Series.
If I try to force enable Windows core isolation through registry I get BAD Image on AMD radeon hd 6970M driver( HypervisorENforcedCodeIntegrity)
So two questions :
1) I have no Intel HD graphics 2000 in device manager , is it fine ? I though i7 2600 have it.
2) Any way to update Radeon HD 6970M driver to support core isolation feature ?
Can upload working dsdt-modified.aml if someone need it.
Update - Changing display brightness in windows does not work.
Update - FOund out that Intel HD 2000 not supported in Windows 10 thats why it's missing in device manager.
Secondly - Found amd drivers for HD6970M on amd website ( latest one with Windows 8.1 64 bit version 14.201.1009 now version )
brithness control in windows 10 works now , though what not working is Night light button( nothing happens) but that's not big deal since u can use AMD Catalyst control panel and change Kelvin monitor settings.
Thank this forum and all who make fix DSDT override !
