Solved I need to get ACPI\INT34BB Driver working in Windows 7

[sjiwh888]

I can't get ACPI\INT34BB Driver working in Windows 7 (Intel(R) Serial IO GPIO Host Controller)
My touchpad also doesn't work likely because of this missing driver

I have a 8th gen intel processor (i5-8265U)
I got other drivers to work on this modern and unsupported laptop by windows 7 thanks to the forum and driver updaters

 

[sjiwh888]

Only this driver left

Hello Luke222


Sorry I can't yet help here.
I'm about to embark on trying to have Win7 run on an HP 250 G7 i5-8265U. I've collected various drivers, mainly the graphics and usb3 ones that may work, but I won't know for about a week yet.


Can you list the drivers you've found that work for you ?

" ... Win7 run on an HP 250 G7 i5-8265U"

Progress to date is quite encouraging.

I used a combination of sources to prepare a Win7 installation USB, in particular with probable drivers. This website, notably SWI2, Win-Raid and MDL. My preference for generating an updated Win7 installation ISO is to use Windows 7 Image Updater (Atak Snajpera, MDL) although I compare the updated drivers for both Boot and Install with SWI2's 7UPv54 and cross-copy more recent ones.

Win 7 installed very quickly off a prepared USB drive (after realising that the G7 EUFI called it a USB hard disc) and then took about 30 minutes to install all the useful updates. I had partitioned and formatted the target HDD as MBR beforehand. This was followed by updating with the most recent Simplix pack.

The now installed HDD is a 1TB SATA SSD, not an NVMe as yet (although the MoBo has the slot). So the NVMe drivers are untested here. 8Gb RAM is installed.

Astonishing to me was the immediate installation of almost all required drivers - audio (Realtek), WLAN (Realtek), mouse, touchpad, keyboard, USB3.1 ports (USB 3/XHCI host controllers drivers in both 7UPv54 and Atak's Windows 7 Updater), Intel Thermal Framework ...

Only two (2) were outstanding in the Device list.

Predictably, the Display Adaptor defaulted to VGA. I tried the Biostar install file for Intel 600+ graphics (win7_8th_i3_i5_Driver_2.0.rar from the Biostar website). This actually worked after adding:

%iKBLULTGT2R% = iSKLD_w7, PCI\VEN_8086&DEV_3EA0

to the Win7 section inf file in the unpacked Graphics folder. The 3EA0 code designates Whiskey Lake adaptors it seems. After installation, the adaptor identified as Intel Iris Plus 655. This edit was suggested here by SWI2 in a Drivers thread. Highest resolution, Aero etc all enabled.

Just one outstanding driver issue left at this point. An "Other Devices" PCI listing, which I'll try to hunt down at some stage - right now I can't find anything that doesn't work properly.

I did wonder why so many devices were correctly installed first go. I did update the installation ISO on an older HP 250 i3 5005U so it seems that HP just repeated a lot of the hardware from the older machine into the newer model. Even my LAN connections were installed correctly.

The speed of the USB3.1 ports is astonishing. The Iris 655 graphics adaptor suits a non-gamer perfectly. Bluntly, thanks to SWI2 here, Win-Raid and MDL, this was actually easy - Win7 on an G7 i5 8265U machine. I hope this helps others.

Hullo Luke222,


There is a basic article which may help at:-
- How to Find Drivers for Unknown Devices in the Device Manager



In the past I have used software called Unknow Devices to find Drivers for unkown H/W.
There are now even 2 versions of the S/W, from different sources, unfortunately with the same name.



One is from SourceForge and one is from "HalfDone".


I have used both and they both work.


Major Geeks have a copy of the latter version (same version nbr I have) at:-
- Download Unknown Devices - MajorGeeks


I am not sure how up-to-date the SourceForge version is, but look for it at SourceForge, if you wish and decide for yourself.



From both of these Softwares you can get the Hardware ID, which is essential for the next stage of the ultimate Search for the Driver.


There are many sites out there which contain a list of HW IDs and their respective details, which will lead you to the next step in the search for the Driver.


From memory, I think ACPI drivers tend to be fairly generic, so this may help in your search.


Good luck,
IHTurbo.

I've also found DeviceInaBox and drp.su/en helpful sites for tracking drivers by device_id.


I've found drivers for the "Other PCI Devices" that weren't there on Win7 installation and added them to the Windows 7 Installation Media Update files. So no outstanding issues left with Win 7 on an Hp250 G7 i5-8265u. Now a quite fast machine.

 

[sjiwh888]

I still need help :shock: There are no touchpad drivers for this laptop officially available

As above, I found a Win7 synaptics driver combination for the touchpad on an HP250 i5-8265U that had listed in Device Manager as your screen dump above showed:


Other PCI Devices (3 listed)


Obviously there's no guarantee these will work on your specific machine. They worked on the HP250 here


1) synaptics smbus-19.3.4.226.zip
2) Intel-FORCED chipset x64x86-10.0.27.zip
3) Intel-FORCED chipset x64x86-10.1.17667.80882-CannonLake-LP-drp.zip


Installed one by one with these steps:



a) Unzip x64 driver into its' own directory
b) Use Device Manager to update driver and search in that directory


I think the zip files came from the Driver Update website, but a standard search will easily find them.


If these don't work on your machine I can't help further.

Check bios for a setting something like BIOS > Main, Touchpad and change it from Advanced to Basic and then save and close.

If you don't have that bios setting , then you will need to try the driver ian has posted above.

There are also many touchpad drivers linked here - scroll down to find the list many for win7

I cant find these 2 files
Can i please have the download link?
Intel-FORCED chipset x64x86-10.0.27.zip
Intel-FORCED chipset x64x86-10.1.17667.80882-CannonLake-LP-drp.zip

Not needed. Intel chipset inf files are cosmetic, they make device manager look pretty.

The Intel Chipset Software Installation Utility is not a driver and does not include drivers.
The Intel Chipset Software Installation Utility gives the product name for the piece of hardware. This information allows the operating system to display the correct name for that piece of hardware in Device Manager.
How do I Use the Intel(R) Chipset Software Installation Utility?



You do need the touchpad drivers.

 

[ian50]

SIW2 is right in that both the Intel-FORCED files contain cosmetic inf files with no .sys or .dll drivers. They did remove the yellow exclamation marks.



My Device Manager now lists under System Devices: Synaptics SMBus Driver with driver file details Smb_driver_Intel.sys and WdfCoInstaller01011.dll


These are the exact files contained in the synaptics-smbus-driver-19-3-4-226.zip reference I listed earlier.


Here (at least for the time being):


Synaptics SMBus Driver v.19.3.4.226, v.19.0.17.142 download for Windows - deviceinbox.com

 

[sjiwh888]

It installs but the touchpad doesn't work and doesn't show up in device manager

 

[sjiwh888]

I gave up.

 

[ian50]

Last possibility, perhaps:


In the Device Manager Details tab for ACPI\INT34BB, instead of Hardware ID's, try Compatible ID's


Sometimes (very occasionally), I've found useful drivers searching for the code from a Compatible ID listing.



Otherwise ...

Again for those who may be interested, I've installed a Crucial P1 M.2 1TB NVMe disk card in the HP250 i5-8265U budget machine running Win7.


That completes the upgrade. I used an updated USB3 Win7 installation card (drivers from SWI2, Win-raid and MDL, plus various other sites ), then ran driver setups for the Intel UHD graphics, the touchpad and finally the NVMe card.



The two interesting bits:


a) the graphics chip, which had defaulted to VGA on Win7 installation, was upgraded by the Biostar installer from Windows tool


An added line in the inf file from this graphics driver setup (recorded in my comments above) allowed the setup to ran straight through. Note though that the Biostar driver has two preconditions: installation of two kbxxxx.msu files and a supplied registry file. Microsoft has thoughtfully removed the msu files from its' repository - very noble of them - but Biostar has links for their own repository (anticipating MS's action, one may surmise). The registry file has a Chinese language name, translated it says: " Install before running driver setup"


b) the Crucial (Micron) NVMe P1 card, while an older model, works fine, with read speeds to about 1750 Mb/s and write speeds about 1500 Mb/s (Crystal Disc benchmarks). There are two pre-requisite kbxxx.msu files to allow the NVMe card to be recognised (both SWI2 here and Win-raid have supplied download links as MS has predictably removed these as well). After recognition on reboot, Micron has a driver file here amongst other sites: Drivers Micron NVMe PCIe Device Driver 2.1.15.56 WHQL
[Micron NVMe Windows Device driver
Release Notes:
April 2020
Software Version 2.1.15.56]
This upgrades the speeds of the card to those recorded above.


I used Macrium Reflect to clone the existing C: drive onto the NVMe card. Once the clone was completed (a surprisingly long time), I turned the machine off, no reboot as there were then 2 active C: drives in the machine, removed the initial C: drive and then rebooted using the NVMe drive. The UEFI BIOS squawked but turning Legacy on and Secure Boot off had it all working properly.



This P1 M.2 NVMe disk is an older model but is now being discounted by dealers. 1TB at 3x the speeds of the older SATA ssd's for AUD$100 seemed a good deal to me.


All up, this HP250 G7 i5-8265U is an 8th gen budget machine with upgraded capability running on Win7. The website here supplied the essential core information to do this, although spread over quite a few threads.

The two kb files for nvme support are in my sig at the bottom of my posts.

The biostar graphics drivers are very useful for 7th and 8th gen intel cpu graphics.
