"Add Resizable BAR support for Nvidia RTX 30 series cards to potentially deliver more performance to gamers in select titles.
When I enable BAR I must disable CSM. Then I don't have in BIOS visible any drive. I can't boot to Windows. SATA drive are invisible also M.2 drive is invisible. When I enable CSM again everything is fine. What I did wrong?
1. My all drives are in GPT mode but I can't boot with csm disabled.
