Did you read the instructions given in post #1 of this thread fully?

Pay particular attention to this step if you've already downloaded & selected the MINIX drivers....

*** Please note, the "802.11 ac WDI SDIO" device is the Wi-Fi device, and when finished manually installing the Wi-Fi driver, you'll have to move 4345r6nvram.txt to the folder C:\Windows\System32\drivers\, and restart the box to make the driver take effect. ***

is always on the forum?

please help me to install wifi and video driver

Yes, the driver package for the Z83-4 is always available for download using the link in post #2 of this forum thread.

Otherwise, the same applies as the previous post, did you follow all of the steps included in the instructions as written in post #1?

Additional information is also available to help guide you through this process if you actually read through this thread from the beginning. Other users have raised the same questions several times over & the answers are already there if you care to read through them ;).
 
Thanks all, must be a google chrome issue? Never mind, worked on edge.
Another option: (with chrome, for example)
1-Right click with the mouse (instead of left click) on the link
2-Select Save link as (see image)
3-download the file to your PC
4-Select keep (see image2)
5-Go to the downloaded folder (archive extractor tool is needed : example winrar) and install the drivers

Having bought the Z83-4 from new, I've just bitten the bullet and installed Win10 21H2 (see below):
Edition Windows 10 Home
Version 21H2
Installed on ‎27/‎06/‎2022
OS build 19044.1806
Experience Windows Feature Experience Pack 120.2212.4180.0

I could only do this successfully as a fresh clean install (not through update facility as no disk space). Apart from the issue of the drive being far too small for any real computing, I cannot sort the SD card driver issue. Up until now, one way or another during various upgrades I have managed to have it working. Not this time - try as I might. Silly question, with all the different links to driver files in the forums (including https://files.theminixforum.com/shared/drivers/Z83-4_CherryTrail-T3-64bit_drivers.zip), what is the actual one for this please. Can someone just give me the name of what I'm to look for? I can work around the TrustInstaller problem, but need to ensure I have the actual correct driver before I start playing around again: "SD Storage Class Controller" yellow triangle and no drive recognised: 'sdbus.inf'??Many thanks - fingers crossed. D
 
For anyone having issues with the latest windows 10 and reimaging your Minix. The solutions provided here didn't work for me specifically but I used SnappyDriver to obtain the drivers needed.
 
I just installed Windows 10 Pro and there is no 802.11 ac WDI SDIO device even showing in device manager to install a replaced driver. Any solutions? Currently no bluetooth or wifi.

UPDATE - updated to 22H2 and it showed up in device manger, then followed directions and wifi now works.
 
I installed the windows 11 pro mini, Can anyone help to install the driver in windows 11, there is no 802.11 ac WDI SDIO device even showing in device manager to install driver.
 
I fixed the issue in a similar manner to what hahnweiler suggested, though there are some necessary added steps.

1) I replaced the dumpsd.sys and sdbus.sys contained in the Windows/system32/Drivers directory, with the copies contained here:
https://files.theminixforum.com/shared/drivers/Z83-4-Driver-Fix_SD_card_cannot_be_seen.zip

2) I replaced the sdstor.sys file contained in that same directory, with the copies contained in the attachment found here:
https://forum.chuwi.com/thread-6634-1-1.html (The attachment in the first post, "SD drivers by nandinhus.zip")
(Note, there are TWO copies of that file within the ZIP. I used the copy found in the "SD_CLASS_STORAGE" sub-directory. )

3) I made all three files read-only (we'll see how well that goes) and restarted. Problem solved.

The tricky part was getting around the TrustedInstaller protection that prevented me from renaming, replacing or deleting the files contained in the Drivers directory. I had to change the advanced security settings of each of the three files, first changing "ownership" of the file from TrustedInstaller to "Administrators", then editing the permission rights deleting TrustedInstaller and giving full access rights to Users. (There's probably better guides online as to how to remove TrustedInstaller protection, but it's not that difficult. In any case, always copy backups of files before messing with these things.)

Anyways, once I changed those settings for all three of those files in the Drivers directory, I was able to rename/move/delete them, and replace them with the "new" system files (from steps 1 and 2.)

Note --- I tried installing these same files by running the INFs included, and by browsing/updating the drivers manually via Device Manager, and neither method worked, among many other attempts. This is the only success I've had. Cheers to MINIX and hahnweiler.
That website link is now dead
 
1. Go to 'Device Manager' by right-click 'This PC' icon on the desktop, and choose 'Manage' option. (See attach picture step1.png)

2. Right-click the driver with a yellow icon, and click 'update driver' option. View attachment 18 (See step1.png)

3. In the prompted window (step2.png), click 'Browse my computer for driver software'.

4. Click 'Browse' to load the driver. Just pick the folder where the driver is located. (See step3.png)
If any user does not know which driver folder to load, just pick the folder that holds all the drivers, so that you won't pick the wrong one.

Please note, the "802.11 ac WDI SDIO" device is the Wi-Fi device, and when finished manually installing the Wi-Fi driver, you'll have to move 4345r6nvram.txt to the folder C:\Windows\System32\drivers\, and restart the box to make the driver take effect.

Bluetooth driver and Wi-Fi driver are both in the "Z83-4 WiFi driver" folder.


The drivers are available from the link below:

All drivers (301MB): https://files.theminixforum.com/shared/drivers/Z83-4_CherryTrail-T3-64bit_drivers.zip

A driver that fixes that the SD card cannot be seen:
https://files.theminixforum.com/shared/drivers/Z83-4-Driver-Fix_SD_card_cannot_be_seen.zip
Hello from the future in 2024, I have an issue with the Wi-FI driver. I am using a NEO Z83-4 Plus V2 system with Windows 10 installed on it.
After downloading the file https://files.theminixforum.com/shared/drivers/Z83-4_CherryTrail-T3-64bit_drivers.zip that contains all drivers, I managed to get rid of most of the unknown devices that had the yellow icon warning in the Device manager app (However there are still 3 devices that when clicking on them and then "update driver", they give an error that "installation could not be made", see unkownDevices.png)

I made sure to follow the instructions for the WI-FI driver (I moved the 4345r6nvram.txt file to the C:\Windows\System32\drivers\ folder and restarted the system). After doing this and going through all the unkwown devices and clicking "update driver" and "Browse my computer for driver software", the system still doesn't have WI-FI and no WI-FI adapter shows up in the "Network adapters" category from the Device manager app (see networkAdapters.png).

I was wondering if any of the 3 still unkown devices could be the wi-fi adapter, but it doesn't seem like it since they are identified as "Serial IO UART controller" and "Sideband Fabric device" (see images Serial IO error and Sideband Fabric error .png)

Could anyone please help with this issue? Thank you in advance.
