I read on some forums, that the Intel nuk had problems with SD as well, same driver etc. (On anniversary) that got fixed through a BIOS update.
So I figured, it might help as well.
There is a BIOS available but it’s packed with a win10 img. My download from Baidu is about 70kb/s tops.
The whole zip is 7,5gb. :/
On the good side, the SD card is recognized in the UEFI shell. I dunno, but sounds like a Windows driver issuee. Tried SanDisk ultra 32gb
