Serial IO GPIO Windows 10 driver on windows 8.1

Recommended Posts

Posted (edited)

Hi,

I can't get these 4 devices working on windows 8.1 and as a consequence the Intel graphics display adapter is not present on device manager and the same for the Touchpad:

ACPI\VEN_INT&DEV_3453

Intel(R) Serial IO GPIO Host Controller - INT3453

ACPI\INT3453\1
ACPI\INT3453\2
ACPI\INT3453\3
ACPI\INT3453\4




This is a new laptop model Lenovo 330-15IGM with default BIOS, you can see BIOS update available on Lenovo's site but I don't want to install it right now because they don't give the option to come back to the previous BIOS version after the installation as I read.
All drivers and Bios updates are here: 
https://pcsupport.lenovo.com/es/en/products/laptops-and-netbooks/300-series/330-15igm/downloads

Direct link to the driver:

https://pcsupport.lenovo.com/es/en/products/LAPTOPS-AND-NETBOOKS/300-SERIES/330-15IGM/downloads/DS503390

https://download.lenovo.com/consumer/mobiles/a8l105af.exe


I tried modifying the w10 inf file to install it on windows 8.1 but I get a yellow mark and this message in the device > properties:
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
{Unable to Load Device Driver}
%hs device driver could not be loaded.
Error Status was 0x%x

I'm currently comparing my INF with two more inf files which are for these hardware ids:


%iaLPSS2_GPIO2.DeviceDesc_0%=iaLPSS2_GPIO2_Device, ACPI\INT344B
%iaLPSS2_GPIO2.DeviceDesc_1%=iaLPSS2_GPIO2_Device, ACPI\INT345D
%iaLPSS2_GPIO2.DeviceDesc_2%=iaLPSS2_GPIO2_Device, ACPI\INT3451

and

%iaLPSS2_GPIO2.DeviceDesc_0%=iaLPSS2_GPIO2_Device, ACPI\INT344B
%iaLPSS2_GPIO2.DeviceDesc_1%=iaLPSS2_GPIO2_Device, ACPI\INT345D

DriverVer=05/04/2015,30.61.1519.07
CatalogFile=iaLPSS2_GPIO2_SKL.cat

This one is compatible with w8+, all the INF is the same as the one I have installed & worked in w10 except for the hardware device ids

DriverVer=06/23/2017,30.100.1725.1
CatalogFile=iaLPSS2_GPIO2_SKL.cat

This other one is only compatible with w10

I'm gonna try with the FeatureScore you posted (after reading about it in the documentation of MS site) looking at this example (https://github.com/bq/web2board/blob/master/pkg/win32/drivers/slabvcp.inf) different driver but an example of how to use the directive in a INF file.

https://docs.microsoft.com/en-us/windows-hardware/drivers/install/inf-featurescore-directive

It's very important for me to use W8.1 (it's not the perfection of it's brother w8.0 which, as experimented users know it's the best MS OS because it has WDDM 1.2 )

 

-Consider: different inf filename but the content is almost the same!-

What can I do? Windows 8.1 runs very fast on this laptop compared to w10.

Thanks,

They have similar IDs but they are different IDs.

So It requires another device driver. :3

Ok, this is the original window 10 x64 driver for INT3453:

https://download.lenovo.com/consumer/mobiles/a8l105af.exe

https://pcsupport.lenovo.com/es/en/products/LAPTOPS-AND-NETBOOKS/300-SERIES/330-15IGM/downloads/DS503390

(the .exe extracts the content of the driver to a folder before the install)

and this is the same driver with .inf modified by me https://www.mediafire.com/file/7zt5hs9bkb4g4hp/drv.zip/file 

May you take a look at the .sys file to see if you can adapt it for w8.1 x64 @blackwingcat or somebody in the forum, please?

Thanks

The GPIO Host Controller should not have anything to do with the touchpad or graphics adapter. It is specifically for the use of I2C, SPI, UART, or GPIO. It is the type of device that, if this is for home use, you can be safe to not even install the driver for it if you won't use those types of interface in Windows. And, as is the case with some mobile platforms (including integrated systems) that use Intel chipsets, the hardware includes features for devices that are not actually usable. That is, the ODMs do not put the connectors onto the PCB that are required for such things.

When you modify a driver, you will break the digital signature on the INF. This will cause problems for modern Windows OS unless you disable the driver signature enforcement.

You can try any of these cabs marked from 2017 on the update catalog:

https://www.catalog.update.microsoft.com/Search.aspx?q=ACPI\INT3453

They use NTamd64.10.0, which would need to be changed to an 8.1 specific (I don't know the text) or just to straight NTamd64 in both places:

[Manufacturer]
%INTEL%=Intel,NTamd64.10.0

[Intel.NTamd64.10.0]
%iaLPSS2_GPIO2.DeviceDesc_2%=iaLPSS2_GPIO2_Device, ACPI\INT3453

But as stated, even Intel admits that GPIO driver on mobile platforms typically just results in the flag going away, and the hardware being largely useless without the physical connections.

Time to get a null (dummy) driver? :dubbio:

So why the graphics card is not detected on windows 8.1?

No display adapter is show on Device Manager 

its an ACPI related question?

Null driver isn't really needed, you can just ignore the fact that the driver isn't installed in Device Manager. I guess if you are OCD you can write a null...

Does the graphics adapter appear for another OS? If so, you can use Device Manager to do a view by connection, to see what parents it has. Windows 8.1 would have the same structure in theory.

Yes, I have all drivers installed and working on w10.

The parent for the Intel Graphics card in Device Manager is:

ACPI\PNP0A08\0

So I need to be sure it is installed and working on w81 or I need to check if this other device has a parent too ?

I searched for the device on DevManView and found this:

PCI Express Root Complex    (Standard system devices)    pci    System        ACPI\PNP0A08\0        0x00000030    0x00000000    No    Yes    3/14/2019 8:14:52 PM    3/14/2019 8:14:52 PM        {00000000-0000-0000-ffff-ffffffffffff}    PCI Express Root Complex    10.0.18343.1    pci.inf    PCI_ROOT    6/21/2006    3/12/2019 9:07:02 PM    
 

The parent for this is: ACPI_HAL\PNP0C08\0

which is:

Microsoft ACPI-Compliant System    Microsoft    ACPI    System        ACPI_HAL\PNP0C08\0        0x00000030    0x00000000    No    Yes    3/14/2019 8:14:52 PM    3/12/2019 9:07:02 PM        {00000000-0000-0000-ffff-ffffffffffff}   Microsoft ACPI-Compliant System    10.0.18343.1    acpi.inf    ACPI_Inst.NT    6/21/2006    3/12/2019 9:07:02 PM    
 

which has this one as a parent:

ACPI x64-based PC    (Standard computers)    \Driver\ACPI_HAL    Computer        ROOT\ACPI_HAL\0000        0x00000000    0x00000000    No    No    3/14/2019 8:14:51 PM            {00000000-0000-0000-FFFF-FFFFFFFFFFFF}    ACPI x64-based PC    10.0.18343.1    hal.inf    ACPI_AMD64_HAL    6/21/2006    3/12/2019 9:07:02 PM

Those are all in-box drivers... I don't think there would be any change, but you can try installing the chipset driver.

These are the devices I see in w10 vs Devices I see on w8 under System devices

I will check 31D7 and 31D6 because the device name is different..

And also I will try to update PCI Express Root Complex considering its the parent of the graphics card

And Windows 10 devices by connection:

As I know the problem is not related to this driver, the problem is the graphics card not detected in w8.1, is tehre any bios dump software to check if is there any bios option to change acpi mode and get it detect detected on windows 8.1 ? @Tripredacus @blackwingcat

Thanks, 

Regards

There are two things relating to that.

1. Never have the need to dump the firmware off the system for that. If there is one on the website, it is good enough. Also in my experience, firmware dumps can have too little or too much data in them as compared to ones provided by the manufacturer.

2. I would never attempt such a thing on a regular system, with no promise of replacement. One wrong thing can brick the notebook. I've done that many of times, but they were not a single system and the hardware was replaced. I would say that without a duplicate system to test learning how to do the thing you want properly, it would be very risky in case you end up doing something wrong.
