Just received the ASRock J4205 and I'm curious if any one has been able to run Win 8.1 on these boards or are the device drivers just not available?

Thanks

Don't know about 8.1, I was able to run Windows 7 on this board - to be able to use Win 7 license for this device and upgrade it for free to Win 10. But it was definitely fiddly to get the Win 7 there, because of no Apollo Lake USB driver for Win 7. I had to use another box to copy the Win 7 installation media directly to SATA hard drive and then mount that hard drive to ASRock J4205, launch the installation from it. I don't know what everything was working in Win 7, I didn't check, because the sole purpose was to upgrade to Win 10. I don't recall details, but network was most likely working, because I was able to achieve the goal .

For future reference you can actually use the Win7 product key for Win 10, so no need to install Win7 first.
