Yes is the same tread
, I did post there about 16MB bioses, the link I posted here is the link address of Reous post, I am on my phone not home, but it worked for me
, Anyway his post is #1590.

I watched ASRock BIOS for the 300th AMD series. They are successfully flashed with the built-in utility Instant Flash + Remove Capsule Security Flash in UBU..

At UBU, I made a change to Removing the Security Capsule. Now capsules in both copies of BIOS are removed.
You can try to flash the original BIOS through Instant Flash, but only update the microcodes and remove the Capsule when exiting the UBU.

UBU v1.77.1 b3
- ASRock - Remove Capsule Secure in both copies of BIOS

Edit:
File removed

@Fernfndo

When motherboards appeared on the Intel 300th series, @lordkag reported that ASRock had updated the Instant Flash. As a result, the method with removing the Security Capsule stopped working. And this now does not work for AMD 400-500+ series.

If i may ask a question please. Does the current tool update the AMD AM4 microcode to agesa 1.0.0.5 on a x570 Asus motherboard?

I am using ubu 1770 & mmt 5.0.0.7
Thank you,
Ant

@antandshell:
It updates it to the most current microcode, but not the AGESA version. If you check in HWInfo it won't be 1.0.0.5 but whatever the BIOS already had like 1.0.0.4b or whatever.

Is the microcode responsible for the 2 fixes i am looking for "improved ddr4 ram & PCI-Express bus stability and interoperability fix" ?
Thank you

From what i gather here it does but i need to know for sure before i modify it. Anyone? "Is the microcode responsible for the 2 fixes i am looking for "improved ddr4 ram & PCI-Express bus stability and interoperability fix" ?

I think no one here can state for wot ur hopping for, regarding to a new revision of an mcode only...mcodes usually addresses security related, distributed for
OEM implementation and combined in firmware, AGESA in ur case it concerns to u.
Later the OEM releases its own version (BIOS) corrected/balanced with the new fixes/adapted regarding the HW design
and then it will release some notes (Believe that small/internal notes will be disregarded) to the end-user side.

I think this is wot ull want to see from ur motherboard manufacturer...But this only my opinion...nothing else!

According to toms hardware the agesa is in the microcode.
Maybe we can get a reply from sonic or Fernando?

@antandshell
I updated the last MSI BIOS with AGESA 1.0.0.4 to the newest microcode and in HWInfo and AIDA64 Extreme it was still 1.0.0.4 for the AGESA version. And this was the microcode extracted from an early AGESA 1.0.0.5 BIOS AND the latest when it was available in the microcode repositories.

Edit: I believe the AGESA version is determined by modules in the BIOS, not the microcode revision. And no way to safely update those modules, even with UEFI Tool, I learned the hard way when I bricked my motherboard. :(

Yes, AGESA is not microcodes, two different things there. AGESA often several modules in BIOS these days
