HP Elitedesk 800 g3 mini

[JohnyDJ]

Hello.

I have some problems with intel HD 630 so there is no acceleration (i5-7500T CPU @ 2.70GHz)

Tried pathing but without any luck, can patching DSDT by you help?

I could not boot with your EFI folder and latest Monterey image so I found EFI for Elitedesk G4 on the internet and I could install the system.

Thank you very much for your help,

kind regards.

Send me iMac.zip

I tried like you suggested and it's working. Patching was done and igpu has acceleration.

The only thing I could not solve is waking from sleep is blank screen.

Can you maybe patch DSDT or I can solve this in the other way?Send me iMac.zip

 

Thank you very much.

Almost everyhing works, woooow!!!Send me iMac 2.zip
I had to change alcid=20 to get audio working, I hope this is ok?

Everything works except waking from sleep, there is no image and second screen on DP cannot be recognized, with patch before it was (not full resoultion though).

Kind regards.

try with -igfxnohdmi and -disablegfxfirmware

in some cases these flags stay work good

No change, maybe is not possible on HD 630, because its not UHD 630...
