When following these instructions - https://www.tonymacx86.com/threads/...ierra-on-any-supported-intel-based-pc.200564/ I found the BIOS settings in these locations - Bios Version F20 *CSM - Located under BIOS, the option only appears when Windows 8/10 Features is set to Windows 8/10 *CFG-Lock - Can’t find it. *Secure Boot Mode - Located under BIOS. *OS Type - Under BIOS, but it’s not called OS Type, it’s called Windows 8/10 Features. *IO SerialPort - Under Peripherals, it’s called Super IO Configuration/Serial Port. *XHCI Handoff - Under Peripherals/USB Configuration. Hope this helps someone!
