I recently upgraded from an old AMD A8-9600 to a new AMD Ryzen 7 5800X, and I'm having some major issues updating my BIOS. I'm trying to update to version 5862 and beyond, but I'm getting a message saying, 'Selected file is not a proper BIOS!' I've managed to update to version 5603 by going step-by-step, but I can't seem to go any further. Could my old CPU be the reason for this issue? What options do I have to successfully update my BIOS? My motherboard is a Prime A320M-K.

Alternatively, you could try contacting the motherboard manufacturer or looking through their website for any FAQs or customer support options. They sometimes have unofficial guides or tools that might help you with the update process. Also, make sure your BIOS file is properly extracted and not corrupted—it’s worth double-checking!
It sounds like your old CPU is indeed causing the problem. The BIOS version you want to install may not support the older CPU, so you could be running into some kind of compatibility issue. Many motherboards require a specific CPU to load the newer BIOS files. I recommend checking if there's a specific BIOS version that supports both your old and new CPUs, so you can make the jump without any hiccups.
