M-Flash MSI Motherboard BIOS Update Guide Including AM5 Sockets

100% WRONG, COMPATIBILITY TAB SHOWS ONLY AVAILABLE RECENT BIOS, THE REST ARE BIOS FOR DIFFERENT CHIPS.

Can i use this method with a freshly built PC (first boot up) or do i need to use the USB in the flash bios port with just the motherboard before hand? I honestly was too scared to use the flash BIOS method without being able to see what is going on. This is my first PC build....

Very helpful. So im doing this now and have a usb port on my motherboard io that says "flash bios". Do I plug my bios update thumbdrive into that usb port specifically?

If I updated to the newest and latest BIOS, does it covers the previous BIOS update that I didn't updated too yet, or I have to do it one at a time?
