A bug in the BIOS EFI runtime? No idea, I use a ASUS X99-PRO/USB3.1 Motherboard with BIOS 3902. https://www.asus.com/Motherboards/X99PROUSB_31/ The last time i tried to update the bios, the bios file was not accepted by the flash util from the bios, most likely a bad file. (Because the download was a zipped version 'X99-PRO-USB31-ASUS-4101.zip' which gave no errors while unpacking)
