Hi Austin,

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.

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
