Question about B550M Steel Legend - 326149

I have just received mine. It came with version 1.00 😐 There is no USB flashback. I think Asrock only offers this on high-end models. Asus and MSI already have it on mid-range boards. Just search for mainboard/brand and "usb flashback".

If you buy this mainboard for Zen3, you should still have the predecessor (Ryzen 3000 series) (WITHOUT GPU) so that you can update.

A processor must be present on this mainboard in order to update the BIOS.
From BIOS version 1.20, published on 26.8.2020, support for Zen 3 is included. At some point, the boards in the shops will have this version (or a newer one), but at the moment you can probably not expect it yet, I think.
