Hello,

I am having a similar issue with SGX. I tried to use the cyberlink advisor but I cannot click on the "not available" result and there is no info icon to the right, so it will not install SGX.

I am running:

Intel Core I5 9400f

ASUS Prime B365M-A

Geforce GT 1030

The Bios in the ASUS board is also set to software controlled. There is no enable choice... Can anyone help further?

Hello AAron1011,

Your issue may be due to your OS being installed in Legacy Mode instead of UEFI mode. Enabling SGX via “Software Controlled” can only work if the OS is booted in EFI mode. We have no way to do the enabling in Legacy Mode, unfortunately.

You can find out which mode your OS is booted in by entering the following command in Power Shell as Administrator:

Get-SecureBootUefi -Name SetupMode

If the command comes back with an error then your OS is booted in Legacy Mode and you will have to do some work to enable SGX, as explained below...

There’s usually a switch in the BIOS to go between EFI and Legacy modes. You can’t simply change and then reboot… the OS has to be installed in that mode. If you simply switch it and reboot, it won’t boot.

There are only two options:

1) Switch to EFI mode in BIOS and re-install Windows in that mode.

OR

2) Switch to EFI mode in BIOS, boot a live EFI aware Linux distribution (most are these days – Linux Mint works), and then run a utility to enable SGX in that environment. We don’t have an “official” tool for Linux to do this. Read this support thread for full instructions: https://github.com/intel/linux-sgx/issues/354
