Dear Smogo,

Greetings, this is ASRock TSD.


The problem is caused by no-integrated graphics support by the Summit Ridge 1200 CPU.

Please refer to the specification (integrated graphics section), AMD 1200 CPU doesn't include integrated graphics. So it is normal that there is no display from onboard graphic.

For your system, an add-on graphics card is required for system setup. Please install a graphics card and check if system can boot properly.


Thanks!

All the best,
ASRock TSD
