Mobo: Asus M5A78LE, no UEFI

I tried yesterday using OpenCore, followed the tutorial extensively but i got a screen with x64 exception red letters. Can't i run OSX?

Try the EFI in this post - https://forum.amd-osx.com/index.php...-690-oc-0-7-6-big-sur-11-6-2.2400/#post-15556

It was created for use with a similar Bulldozer FX CPU.
