Question Motherboard apparently has a customized BIOS ?

[GENESY]

I have an MSI B450 GAMING PLUS MAX motherboard. My problem is that it apparently has a customized BIOS which does not allow me to update it to support 5000 series processors. The BIOS version that it has is E7B86AZ1.HQ2 with a date of 01/19/2020. Do you know how to fix that problem so I can update it to new versions?

Welcome to the forums, newcomer!

By customized, can you elaborate? Was the motherboard part of a prebuilt you'd purchased?

Are you sure about the make and model of your motherboard?

Since I don't see that BIOS version on the product support page. If your motherboard was provided as part of a prebuilt, then you might want to avoid tampering with it since a bricked motherboard would mean you going out to have to buy a new motherboard/BIOS chip and effectively losing warranty on your prebuilt if it was recently purchased. I'm merely going by an assumption.

If you've got the make and model of the motherboard correct, then you can follow through this guide;

but please be wary of the possibility of losing warranty on your board.

Mind sharing the specs to your build like so:

Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model.

You might need to find somebody with BIOS writing apparatus with a clamp for direct connection to BIOS chip. Every PC service should have one.
Just one example.
