Huawei MateStation

Hello! How can I get my Huawei MateStation S with B550 chip to work with AMD Ryzen 7 5700G processor? Can anyone help me with this? I guess I should inject the microcode of the CPU into the BIOS

Usually is not enough, AGESA has its own role in AMD chipsets.
AGESA is a “boogieman” on the mod scene, so dont count on it, still go ahead and update/add mcodes
as long as you know how to recover from failures and have the experience on this area.

BIOS updates for the Cesanne core are constantly being released by major motherboard manufacturers. So there must be a specialist who knows how to do this. I myself am not one of them. I’m looking for someone who can do this, either for the pleasure of coding, or for a bit of glory for being able to do it, or for some remuneration. I have already bought the processor, I don’t want it to go to waste.

As the common user doesnt have any clue of the AGESA role…they dont like to hear the “Cant be done…” anwser, so sorry and welcome to markting strategy and all that can be built/break/impossible by humans. Most of the modders would like access to bios engineering lab tools…unreleased for public.
Yes…youre rigth…your issue my friend is that the OEM didnt released or doesnt have intention to… publish a new bios for their clients with updates or support for newer generations. So assemble a large costumer database and go do some pressure on HUAWEY.
Now, let me explain to you again, i didnt said that a mod bios cant be done, i said its very hard to achieve and very few users(modders) can do it or have successful reports on it, due to the AGESA module being a pain in the ass to update/replace/etc…
Go search the web on the subject, also theres a dedicated thread on overclockers forum to AGESA, good luck on it.

PS: You should wait for another user opinion and not loose your hopes based on my statements.
