Greetings dobbylan,
Thanks for sharing your post. Currently there is no ETA for a BIOS update for the X99 WS motherboard's UEFI in conjunction with Intel Core i7 X-series processors. ASUS R&D is working diligently on getting the UEFI build ready for the Broadwell-E release. Please wait patiently as the release will become available at a later date.
