It's very convenience to update the CPU microcode by UBU and mmtools,but this bios made me confused.
I could not update the CPU microcode by the tools above.
Could someone help me?Thanks!!!

@gloobox - Is that maybe a bad dump? ME Region is defined, but all zeros and shows as "unidentifiable" in MEA This is Insyde BIOS, so AMI Tools not going to work. Microcodes are stored in second main padding in BIOS region, when viewing BIOS with UEFITool
Be careful when editing/adding, DMI Data is also stored in this padding file (starting @14000h) so watch you don't overwrite if microcode sizes increase, should be plenty of room there for any changes though, so not to much to worry about.

If you need me to update them let me know

@Lost_N_BIOS
yeah,it's Insyde BIOS
Could you help me to upgrade this CPU microcode 206A7 to the newest one?Thanks?
BTW,what tool do you use to mod the Insyde BIOS?

@gloobox - all Insyde BIOS different, sometimes use EZH20 but only very rarely, usually UEFITool and hex editor. For this one, and to mod ucodes, UEFITool and hex editor only.
It's probably possible via straight hex edit, since in this BIOS the uCodes are in a non compressed padding file, but not ideal to do that so I didn't check
Here all microcode updated - http://s000.tinyupload.com/index.php?fil...367333174909757

@Lost_N_BIOS
Thanks,the machine's sb is hm65 which supports 2820qm in other model,but it didn't.I think the reason is mainly the old bios's CPU mc.
I will give you feedback and thanks again!!!

You're welcome. Maybe update ME FW too?

Hi, I realize I'm hijacking an old thread, but my question also relates to updating the microcode in the BIOS for a 206A7 CPUID. I have several of these laptops in service, motherboard Twinhead R13H with an Intel Core i7-2655LE CPU. The issue I've run into is instability in Windows 10 version 2004 (20H1) and above. The rarity of this motherboard prompted me to investigate whether other systems with comparable hardware were experiencing similar issues, which led me to find what appeared to be a close analog. A forum with countless users detailing the same problem with the AsRock P67 Pro3 motherboard. Complete stability in Windows 10 1909, and random KMODE Exception BSOD's in V. 20H1 and above. Further research uncovered similar user reports with 2nd Gen i7 processors and these recent Win 10 feature upgrades.

In the case of the P67 Pro 3, a Beta BIOS update was provided that apparently resolved this issue, and the changelog only lists a single entry "CPU Microcode Update". I'm sure this is an overly simplistic assumption, but this evidence has me tentatively convinced that a CPU Microcode update in the BIOS of the Twinhead board might resolve the stability issue as well. Unfortunately in my case the Manufacturer no longer exists, so an OEM BIOS update will never be released.

Although it may not be related, it's worth mentioning that the Windows 10 task manager also reports 100% CPU load continuously, and following this update: KB5003169 causes it to misreport the CPU frequency as an insane value (ie 847639765.50GHz).

I was planning to attempt the BIOS mod myself, but came across multiple warnings on this site cautioning against using UBU with mobile chipsets, so I thought it best to first reach out to the community for guidance. Any help would be greatly appreciated.

Let me know what resources I should provide and I'll post download links.
