Pro Gaming UEFI secure boot problem

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

   I tried setup secure boot using custom certificates and I got a problem.Each time that I enable EFI Secure Boot, the bios says that will disable CSM and I agree but it does the inverse thing and makes me impossible to boot the graphic card in EFI video mode making me impossible to passthrough to a kvm virtual machine so I have to disable CSM Video and that makes Secure Boot works.
As I disable CSM Video, I cannot use the BIOS Setup tool as I haven't video until the vm initialize the graphic card.

	Dear tmc_00, Greetings, this is ASRock TSD. If you would like to enabled UEFI Secure Boot option, please make sure the system including VGA card and OS could also support pure UEFI mode. As it is an auto rule of AMI's BIOS, so please check if the system could run at pure UEFI before enable this function firstly. Thanks! All the best, ASRock TSD

	tmc_00, please post all your system specifications. I suggest you do so as I have in my signature. I am really surprised ASRock_TSD did not ask for this. Enjoy, John.
