[SOLVED] Problems with drivers on intel NUC with IRIS graphics card, I219-V ethernet, Wireless-AC 9560 wifi

I recently had some issues trying to run slackware64-14.2 on a intel NUC8i5BEH (released Q3 2018): it's not so new so I was quite surprised (and this issue probably also hits many other NUC owners with IRIS graphics card, I219-V ethernet NIC or newer or Wireless-AC 9560 wifi/bt NIC or newer )

With an out of the box slackware64-14.2 install the following things did not work:

• Eternet (no nic shows up no matter what intel driver you try to use)
• Wifi/Bluetooth (no nic shows up no matter what intel driver you try to use)
• Xorg fails to start (complaining there is no available display)

Apparently the 4.4 kernels just do not support some of the specific hardware that some NUCs.

If you want to run slackware64-14.2 you have a couple of options both require borrowing elilo from slackware64-current:

1. compile a newer kernel (for me 4.19 worked not sure if anything older then that will work)
2. borrow kernel from slackware64-current

The uSD card reader works once installation is complete (I was able to boot the installer from the a uSD card but during the installation I was unable to access it to fetch the packages and failed to find a way to manually load the required modules to get it to work)

Alternatively if you are happy to run slackware64-current that should work out of the box.

NB: To get the installer to boot you probably need to disable secure boot in the BIOS
Hopefully this information will save other NUC owners a few headaches ;)
