ACPI mod request for vga Intel UHD Graphics 600 detection

[quote="voug, post:60, topic:33187"] This is a compilation of my progress trying to get Intel(R) UHD Graphics 600 working (Gemini Lake Gen9) on a Windows 8.0/8.1 or last Windows 10 beta with Windows 8 taskbar and theme and WDDM 1.3 (10.0.9888):

(This post can help you to get the GPU detected on w8.0 and w8.1 but with yellow marks)

To get GPU detected on Device manager
1 - Extract these files from Windows build 6.3.9369 iso (w8.1 beta):

c:\Windows\INF\intelpep.inf
c:\Windows\INF\intelpep.PNF
c:\Windows\System32\drivers\intelpep.sys
c:\Windows\system32\drivers\intelppm.sys


2 - Copy/replace these files in installed 10.0.9888 (last w10 beta with 8 taskbar and theme)
You can install it without BSODs with WinNTSetup and then renaming these files & also the folder: c:\Windows\System32\DriverStore\FileRepository\intelpep.inf_amd64_549e2067be3548c5)

3 - Now you have UHD 600 detected on Device manager without yellow marks as "Basic Display Adapter" and device ID it's detected cause it's PCI\VEN_8086&DEV_3185 !


4 - At this point I tried modding different .INF files, most of them give me black screen. It's better a black screen than a GPU not detected cause it means the driver it's installed for the Device ID and, at least, it's partially working.

Versions I tried:

- Intel HD & Iris Graphics Drivers Version 22.20.16.4675 WHQL x64 (This one works fine in w10 rtm & 10.0.10586)

Other versions I played with adding and removing what @DeathBringer told me here: Intel UHD 600 on Windows 8.1 Help

- 4505 (intel_vga_4505_64(www.station-drivers.com))
- 4839 (intel_vga__21.20.16.4839-64(station-drivers.com))
- 22.20.16.4675_mod_win8_kabylake
- SMXDIY_Win64_15.45.27.5068_Beta_4.0
- SMXDIY_Win64_15.45.27.5068_Beta_4.0_signature
- win64_15.45.33.5164 --> Problem installing intel UHD 600 on Win7
- Intel-FORCED-6Xx64-HD600_21.20.16.5077
- win7_8th_i3_i5_Driver_2.0_biostar
- win7_8th_i3_i5_Driver_2.0

IMPORTANT: WIth one of these drivers I get, one day, the blue login background with lot of squares on the screen showing part of the name of the user, I mean something like https://www.howtogeek.com/wp-content/upl...s-8.1-login.png but I don't remember which driver it was. So I'm sure it's possible to get the an Intel UHD 600 driver working for this GPU at least in 9888 build which have WDDM 1.3

Also if anybody found this post interesting and wants to try to get it working I have some .txt files with notes and links:

[OFFER] 7th/8th Gen. Intel GPU drivers for Win7/8.1

https://www.texpion.com/2018/06/Intel-7t...ws-7-8-8.1.html

"I have got it to work in this way with v21.20.16.4860 (11/15/2017) or in the above terms [win64_15.45.23.4860] which shows as "Intel HD Graphics 630" in Device Manager. You can just copy the Windows 7 section from an older version into the newer versions including the header line "%Intel% = IntelGfx, NTamd64.6.1, NTamd64.6.2, NTamd64.6.3, NTamd64.10.0, NTamd64.10.0...14393" "

Another test I have done some months ago was porting the pci.sys to a different build which, at the beginning doesn't detected the GPU.

If you think you can help me determine why I get the black screen ? Maybe with the Intel LOG file?

I have also read about intelppm and hal in threads about installing XP on modern hardware:

https://www.tenforums.com/general-suppor...odern-pc-6.html
"The archive contains hal.dll and intelppm.sys timer fix for Intel"

_____

All this information is to get this ID working:

%iGLKGT2E12% = iSKLD_w81, PCI\VEN_8086&DEV_3185

Currently I get it detected with a black screen

Thanks to all,

Regards!

Maybe some users from ACPI mod thread know if I need to replace more .sys files ? @infuscomus @diderius6

Edited:

You can also search for it's previous Gen GPU: %iBXTGTP12% = iBXTD_w7, PCIVEN_8086&DEV_5A85

If I put acpi.sys from 9369 or 9200, I can see the display adapter on Device Manager of 9600 (windows 8.1) but with code 51: This device is currently waiting on another device or set of devices to start.

__

Edit:
If I put ONLY acpi.sys (without intelpep.sys and intelppm.sys) I get:

This device is disabled because the firmware of the device did not give it the required resources. (Code 29)
___

So I'm gonna play again with 9888


Where I can get more info about intelpep.sys and acpi.sys related to Intel HD/UHD Graphics ?
