[SOLVED] Need help updating ASRock x570 Steel Legend BIOS

Dec 14, 2020

I'm trying to get my hands on a CPU to update the BIOS for it to be compatible with my Ryzen 5 5600X but I have a few questions.

On their website it is written that "To support Renoir/Ryzen™ 5000 processors, it requires to update the BIOS with Matisse CPU. "
But after that is is written "If you use Pinnacle Ridge or Picasso, please refer to the "Steps to Update Renoir/ Ryzen™ 5000 Supported BIOS" to update the BIOS. "

ASRock Website

So does that mean that I absolutely need a 3000 (Matisse) CPU to update ? Or can I go with a Pinnacle Ridge CPU (say a Ryzen 5 1600) ?
The latter would be great because I can buy a CPU and return it for 90% of the price, therefore I'll go with the cheaper option.

I did ask AMD for a boot kit but they haven't responded in one week, despite my emails.

Thanks in advance !
