Pcpartpicker warning help

Hello,

So I'm trying to build my first pc and I was checking if everything in my cart was compatibility. I ran into a warning and was wondering if someone could help me out or explain what's wrong.

Warning - "Some AMD B550 chipset motherboards may need a BIOS update prior to using Vermeer CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions."

My list: PcPartPicker
