AMD has released a new and official BIOS update for both the Radeon R9 Fury X and Radeon R9 Nano graphics cards which brings improved UEFI BIOS support.
An improved UEFI BIOS support is needed in order for a graphics card to run without CSM at the system-BIOS end and enabling OS features like Secure Boot. According to some early report, the new BIOS also brings an improved overclocking stability on some graphics cards.
Most, if not all, AMD AiB partners are already shipping their Radeon R9 Fury series graphics cards with a new UEFI-ready BIOS and in case you have bought your own earlier you should update it accordingly.
