# BIOS Settings

### Secure Boot

The setup process installs a development kernel with the required SGX features enabled. This kernel is not signed. Secure Boot must be set to **DISABLED** in your BIOS configuration to allow it to boot.

### SGX

A bios upgrade might be necessary for your system to activate SGX support. Please consult the hardware manufacturer.\
Software Guard Extension (SGX) must be set to **ENABLED** in the system BIOS.

If your CPU or System/BIOS lacks SGX support, please consult the section on the topic to find compatible hardware:
