X370 Taichi CSM issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

I have an X370 Taichi that I am not able to disable CSM mode so that I can set Secure Boot. I have another X370 and was able to do it with that one so I am knowledgeable with the process. Every time I set CSM to disable the BIOS will freeze when I go back into it. I was able to get an update push from Microsoft for Windows 11 and install it but I know I really need to setup secure boot. I only have one drive attached, Samsung 970 EVOPlus M.2 1tb. It's formatted GPT. The BIOS has UEFI mode set, TPM 2.0 is set as per TPM.msc and AMD ftpm switch is set. I am running BIOS 7.3 and I upgraded the CPU to Ryzen 7 5800X. If I disconnect the M.2 and set the CSM to disable it will still freeze. So is there anything else I can try?
