Solved Comet Lake Windows 7

[joeyc100]

Hi,
I am running Windows 7x64 on an H310t thin mini-ITX motherboard with an I3-8100t 4-core cpu (8th Gen Coffee Lake).
The only installation problem was the onchip UHD graphics 630 driver which would not install for Win 7.
But, someone discovered that a line "%iKBLULTGT2R% = iSKLD_w7, PCI\VEN_8086&DEV_3EA0" ( no quotes) added to the --
;=====================================================================
; Windows 7 Install - DT Only
;=====================================================================
section of the igdkmd64.inf file in the driver folder allowed the driver to install and operate on a 7th gen Kaby Lake processor. Further, 8th gen Coffee Lake accepted the mod as well.
ASUS no longer makes H310t boards; they have moved on to H410t with 10th gen Comet Lake cpus. But these have the same UHD graphics 630 onchip package.
Does anyone know if the mod will work for Comet Lake as well?
Joey.

The biostar drivers work beautifully for intel 7th and 8th gen processors igpu.

Canonkong has some modded drivers for intel 9th gen processors igpu

I am not aware of any for intel 10 or 11 gen. You would want a separate graphics card

 

[joeyc100]

Some video card drivers will not install without a graphics accelerator installed first.
In any event, there is no room for any video card on this thin mini-ITX board.
It is interesting that the only obstacle to installing a 630 driver in an 8th gen processor was a declarative statement.

Success!!
Windows 7x64 Ultimate has been installed on a 10th gen Comet Lake board with an I3-10100.
The Kaby Lake video driver modified with a DEV_9BC8 declaration has installed along with it's DisplayAudio driver for HDMI. The USB 3_WIN7_2021 and Realtek Lan drivers are in, and only the chipset driver cannot be found. The chipset appears to work properly without it.
Much thanks to Yaron and SIW2 for their help.
I don't know how to mark this thread as solved

Here is all the Comet Lake and Whiskey Lake ID codes under the Windows 7 Install section in igdlh64.inf that I found in a modded UHD620 driver (which also seems to work for a UHD630 chip):

; CML
%INTEL_DEV_9B41% = iSKLD_w7, PCI\VEN_8086&DEV_9B41
%INTEL_DEV_9B21% = iSKLD_w7, PCI\VEN_8086&DEV_9B21
%INTEL_DEV_9BCA% = iSKLD_w7, PCI\VEN_8086&DEV_9BCA
%INTEL_DEV_9BAA% = iSKLD_w7, PCI\VEN_8086&DEV_9BAA
%INTEL_DEV_9BCC% = iSKLD_w7, PCI\VEN_8086&DEV_9BCC
%INTEL_DEV_9BAC% = iSKLD_w7, PCI\VEN_8086&DEV_9BAC
%INTEL_DEV_9BC5% = iSKLD_w7, PCI\VEN_8086&DEV_9BC5
%INTEL_DEV_9BC8% = iSKLD_w7, PCI\VEN_8086&DEV_9BC8
%INTEL_DEV_9BA8% = iSKLD_w7, PCI\VEN_8086&DEV_9BA8
%INTEL_DEV_9BC4% = iSKLD_w7, PCI\VEN_8086&DEV_9BC4
%INTEL_DEV_9BC6% = iSKLD_w7, PCI\VEN_8086&DEV_9BC6
%INTEL_DEV_9BE6% = iSKLD_w7, PCI\VEN_8086&DEV_9BE6
%INTEL_DEV_9BF6% = iSKLD_w7, PCI\VEN_8086&DEV_9BF6

; WHL
%iWHLULTGT2U42U2F2% = iSKLD_w7, PCI\VEN_8086&DEV_3EA0
%iWHLULTGT1U41FU2F1F% = iSKLD_w7, PCI\VEN_8086&DEV_3EA1

Good persistence, joeyc100 !

Which kabylake driver ?

 

[joeyc100]

I got this from Intel back last April
Intel(R) Graphics Driver for Windows* [15.45]
iKBLULTGT2F = "Intel(R) HD Graphics 620"
%iKBLULTGT2F% = iSKLD_w7, PCI\VEN_8086&DEV_5917

It might have been for Sky Lake and 5917 modified it for Kaby Lake, and 3EA0 for Coffee Lake.
I also got a driver from your posting and that may have been the one finally used for the H310 board.
I have spent the last few weeks working on Comet Lake for an H410, and it's all a blur.

You could see which driver version your 410 mobo with I3-10100 is successfully using

 

[joeyc100]

The same one that you show: 21.20.16.4839

 

[SIW2]

Can you zip up and share the inf that worked ?

 

[joeyc100]

I backtracked all of my research and found out that It's the one that you showed a link on your 6July 2019 reply to Yaron. The link is to

biostar.com.tw/app/en/ev...Driver_2.0.rar

(I left off the https.www. stuff)
It is for a UHD620 and that is what shows up in the Device Manager.
But it works on a UHD630 as well.

By the way, what is the source of
USB3_WIN7_2021
and can it be had in the nominal 8-file bundle (2 each: .cap, .inf, .sys, and .man)?
Joe,

As an epilogue, I came across an Intel chipset driver 10.1.17 which installed. So that gave me chipset, USB, audio, LAN and graphics drivers in all.
Thanks for all the help.
Joe.
