Note:
For those customers that enable SGX function on R750, R750XA, R650, C6520, MX750c, R450, R550, R650xs, R750xs, T550, XR11, or XR12, do not roll back the BIOS to older versions. An issue that is discovered within Intel microcode may cause TCB recovery failure and result in a system to stop responding. By default, SGX function is disabled. To determine if SGX function is enabled:
  • From the BIOS - Systems Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSI) > System Options > Processor Options > Intel Software Guard Extensions (SGX) and press Enter.
  • If it is set to Enabled or software controlled, then the SGX function is enabled.
