I was checking this thread and I would like to double check if the information provided worked for you.
I look forward to hearing from you.
Looks like Processor Intel(R) Core (TM) i7 CPU Q820 @ 1.73 GHz does not support AES instruction
I was asking How can we enable that? Is there any BIOS update available for that?
I was checking about it and Intel® Core ™ i7 CPU Q820 and it does not support AES feature, there is not a way to enable this feature since it was not built with this option.
If there is anything else you need, please let me know.
