How to fix it
Intel® Software Guard Extensions (Intel® SGX) is an Intel technology for application developers who are seeking to protect select code and data from disclosure or modification.
The SGX drivers are currently available on at Intel® Software Guard Extensions (Intel® SGX) Driver for Windows*.
If you don't require Intel SGX, you are able to disable the SGX Security option in the board BIOS.
| Notes | The Intel® Software Guard Extensions (Intel® SGX) feature doesn't have a dependency on the operating system when disabled. If you're not required to use the Intel® SGX, we recommend you disable it in BIOS.
If your Intel® Server System is Intel® Server System LR1304SPCFSGX1, refer to its Intel SGX Server Block solution brief. |
