My first attempt and no luck at the moment, it just gives me a black screen. This unit has had failed Dragoncity PCB and Piggy Back Bios mods, hence the...

Done it on the other unit, but I can only boot into one of the BIOS's. Did I hook it up the toggle switch wrong? ![20250227_143959~2.JPG](https://github.com/user-attachments/assets/57d75270-7031-472e-bf78-c1421a868839) ![20250227_154742~2.JPG](https://github.com/user-attachments/assets/858f65dd-580c-48e3-818d-f36bf8dffdea) ![20250227_154924~2.JPG](https://github.com/user-attachments/assets/4679180b-6c32-4477-880d-0fd89739c801) ![20250227_154929~2.JPG](https://github.com/user-attachments/assets/c3e94a51-8728-4572-9b8f-7f1f9751ffe0) ![20250227_154933~2.JPG](https://github.com/user-attachments/assets/08c76f76-424e-4b41-b5c8-69c4b92d90b4)...
