	This is a warning to users with video cards older than GTX 7xx (GT7xx including) and AMD 2xx Latest BIOS versions in the 4.xx range that offer support for Raven Ridge removed the CSM module for video boot with older not GOP bios, so if you plug in a video card without GOP (UEFI)/Hybrid BIOS you will have no signal on the monitor. This is regardless of CPU, this affects Summit/Pinnacle/Bristol/Raven Ridge, its just that ASRock decided to remove the CSM module from the current UEFI versions. Some of the GTX 680/690 will have GOP/Hybrid bios, some do not, some HD7870/7950/7970 have Hybrid bios but many do not. As far as the HD7990 is concerned it comes with UEFI bios from the factory. All HD6xxx have older bios so they will not boot. Just a heads-up for anyone trying a video card from those series on a ASRock AM4 motherboard with UEFI in the 4.xx range, the 2.xx, 3.xx range has the CSM module present so they are not affected.
