Hello, I'm planning to build a new pc on B550 or B450 AM4 motherboard which obviously has UEFI support. (no internal videocore in AMD CPU)
Since videocard market is weird atm, I'm planning to use my 10-years old videocard with no UEFI support on it.

So If I install it in my new PC, will it load with no problems? I mean would Motherboard choose CSM mode by itself automatically with first startup (because I dont have any other new cards to launch with it and change the mode to CSM).
And another question, will I be able to install GPT Win10 on my new nvme with that CSM mode or not?
