Here are the information. 1. - Here is the spec Intel(R) Xeon(R) CPU D-1557 @ 1.50GHz RAM : 32GB (Is this the problem? I already saw for the controller 64GB RAM is needed, but I'm not sure, cause the installation was just stuck literally, SSD : 500GB SuperMicro - Bios Setting: I enabled and disabled as the instruction said. And at first try, I didn't used UEFI, after failure, I changed it into UEFI, but the result was same. I enabled VTx/Iommu enable or not ? 2. I used bare metal one.. however when I pressed the buttons, nothing happened. And the controller-1 is just stopped as I said before. Thank you for helping me :) Best Regards, Jaewook.
