@Fiox89:
On the basis of the 64bit Intel Serial IO Win10 drivers, which have been posted by our new Forum member HsXJ1mi5U0, I have tried to compose mod+signed Intel Serial IO drivers, which may be usable with your system running Win7 x64.
Please try the attached driverpack. You may only need the 3 files named "iaLPSS2_I2C_SKL" having 3 different extensions.
Don't forget to import the included Win-RAID CA Certificate (if not already done previously) and to report your test result here.


@HsXJ1mi5U0:
If you should have access to the 32bit Intel Serial IO drivers for Win10, please attach them as well.
Thanks in advance!

Hi Fernando, thanks for your work. I installed the driver on A160 / A161 device, but after the installation I have a warning about digital signature. I added the win-mod certificate with the script by Zwulf following your guide. I also had the signature check popup during the installation.

This is the current situation, the driver can be installed correctly but then I have this error

@Fiox89:
Did you get the message, that the Win-RAID CA Certificate has been successfully imported?
You have to import the Win-RAID CA Certificate before you start with the installation of the mod+signed driver.
If you should have done it thereafter, you may have to start the driver installation from scratch (after having re-installed the previously used driver).
Please check the digital signature details of the file named ialpss2_i2c_skl.cat. After having done a right-click onto it, chosen the option "Properties" and hit the tab "Digital Signatures", it looks like this:

It looks like the certificate is present as expected. Please take a look at the attached file.

However, just to be sure I tried the following: restored manually the Intel 100 series drivers for all the devices, reboot, installed again the certificate using the script in the file you attached above, reboot, installed your driver, reboot. The results seems identic, I don't know if I miss somethind during the procedure

p.s.

Do you mean ialpss2_i2c_skl right?

@Fiox89:
When you have executed the ImportCertificate.cmd file as Admin, you should have seen a DOS box, where you are asked, whether you trust this Certificate. After having typed "Y" (for Yes), you will get the message, that "Win-RAID CA" has been added to the "TrustedRootCertificationAuthorities" (or similar),
If you haven't gotten the option to type "Y" and didn't see the content of any DOS box, the import of the Certificate failed (probably due to the too long path to the Certificate).
In this case do the following:
1. Copy the folder "Win-RAID CA Certificate" into the root of drive C.
2. Open the just created folder C:\Win-RAID CA Certificate", right-click onto the file named "ImportCertificate.cmd" and choose the option "Run as Admin".
3. Type "Y", when prompted, and read the final text with the result of the import procedure.
4. Repeat the driver installation.

If you should still see yellow flagged Intel chipset devices DEV_A160 and DEV_A161, press the "Shift" key while choosing the "Reboot" option.
Aftfter the reboot you will see the "Advanced Startup Options". Press "F7" (= Disable Driver Sigature Enhancement) and look into the Device Manager once the reboot is completed.

Yes, it was a typo.

Hi Fernando. I'm sure the procedure is how you described it and I checked the script output. I performed the procedure again following the steps, and I can see this message "the certificate is already present in the archive".

I disabled the driver signature, and now installing the driver I have another error. "The device driver can not be loaded for this hardware. The driver may be damaged or missing."

@Fiox89:
It is a pity, that the mod+signed driver didn't work.
Another idea: Take the original Win10 driver and force the installation by using the "Let me pick..." >"Have Disk" option and navigating to the related INF file for your DEV_A160/A161 devices.

#39 RE: Intel I/O drivers and Touchpad in Windows 7 - Asus Precision Touchpad by HsXJ1mi5U0 23.07.2018 13:11

Asus official not supported Win10-32, on the DVD and website no drivers for W10-32, on the Intel website only for NUCs https://downloadcenter.intel.com/downloa...r-for-Windows-7-
But there is drivers for both Win7-32&64 from Dell https://www.dell.com/support/home/lv/en/...?driverId=R47PT

I currently no access to this laptop, he was not my, so can't test your mod.

No luck, I can't install the driver of Win10.

This is the only way I can make some kind of progress. I can install the Dell driver with the setup, or manually only for the devices A160/A161, and the two devices appears without problem. At this point a new unknown device appears in the list, this is the Elan1200.

Maybe the system is in confusion because more than one device transits on A161, serial I/O and mouse? only a hypothesis, since even the Elan1200 device reports A161 as device indication

p.s. additional info, from driver scan I can see that Elan1200 have a "compatible" device, PNP0C50

Maybe disable mouse and serial I/O in the BIOS if you can, would that help the conflict, so you could get further details?

Hi Lost_N_BIOS. I can disable the Internal pointing device, but about the Serial I/O I have only these options of Security : Lock / Unlock. I have attached a couple of photos

Disabling the Internal pointing device hides the unknown device currently present in devices management

What about disable USB? I was thinking only about trying to eliminate some of the devices you mentioned, so you could maybe find a easier way to install the driver without I/O or IRQ conflicts (ie less devices on A161)

For what I can understand, if I disable the A160/A161 serial I/O, the Elan1200 touchpad device disappears, so I think the two thing are connected somehow. Maybe I'm wrong, but this is what I saw until now.

Inside the bios, related to USB, I have these: Legacy usb, USB Mass storage driver support (disabling the second option does not change anything, apparently at least.)

The others settings abous usb are attached on the previous photos, no other settings on usb

Do you think I was correct, if we could disable Serial I/O then only Elan1200 would be using that IRQ? Does this tablet have a serial I/O port, if not what else is that used for, only the Elan1200? Or maybe SD or Fingerprint device?

Do you already have Intel ME drivers and Intel INF Chipset installed, that way everything is detected properly?

I see in BIOS Serial I/O is used for UART and debugging connections (IHS/GNSS and DCI over USB3). ISH Controller is enabled. There is a setting "Serial IRQ" set to Quiet (other option is Continuous), mainly mentioning all this in case any of it helps or rings a bell for Fernando to advise on changing any of that

In the specific serial I/O config section of the BIOS, which there is a ton of settings, I see Touch Panel can be changed from SPI touch to IC2 touch, that would probably change something in what you guys are messing with. Most are set to APIC Interrupt mode if this matters (not shown in image) other option is GPIO mode


I also see this for "Sensor Hub Type"


Heads up if you ever use the "Secure Erase" option in the BIOS, it's set to "Simulate" instead of "Real" so maybe remove HDD/SDD and secure erase on a desktop system!
