Hello guys, I have problem with my motherboard ASRock B450 fatal1ty gaming k4. When i set CSM to disabled, I have black screen in BIOS and POST. I found that i must disable FULL HD BIOS. But after that I realized that my BIOS is alway displays in high resolution. I found same problem, but on diferent motherboard: http://forum.asrock.com/forum_posts.asp?TID=9694&title=z370-fatal1ty-itx-bios-310-with-csm-disabled is there any solution for that?
