@Birraque :
Welcome to the Win-RAID Forum!
I don’t know. Why don’t you try it yourself (after having extracted the BIOS file from the EXE archive)? As long as you don’t flash the modded BIOS into the BIOS chip of your Lenovo Yoga, there is no reason to worry about anything.

I have patched my x79 Asus mainboard X79-Deluxe with latest 42A patch for Ivy bridge (Xeon e5-2658 v2 on mine) processors, with the UBU_v1_69_10_1
The Meltdown and Spectre bug test now says: Your processor is safe! Spectre green with a tick and Meltdown green with a tick.
Spectre was red with a cross before updating my bios.
The Meltdown patched with software by Microsoft
windows6.1-kb4056897-x64_2af35062f69ce80c4cd6eef030eda31ca5c109ed.msu
and
ie11-windows6.1-kb4056568-x64_f4b6afadf114dc3bd5498a64256e4cdc5e7e7576.msu
latest nVidia driver
390.65-desktop-win8-win7-64bit-international-whql.exe
also installed.
The Windows test program can be downloaded by: https://www.ashampoo.com/en/usd/pin/1304…own-cpu-checker
Thank you very much for this release, it has now an exceptional importance. Good going…
Thank you so much for coming back SoniX; I was able to mod all my Z97 MSI motherboards with uCode 23 for Haswells and hope you are doing well healthwise.
@SoniX
Here is a little feedback for the test version:
I tried the v1.69.10.1 and found a few bugs:
1- Opening my bios with UBU, MMTool gets stuck open saying “file not found”.
After closing MMTool and telling UBU to continue anyway, i find the second bug that is probably related to the first:
2- Option 7 (Cpu microcodes) produce the message "Error: file tmp\cpuffs.tmp was not found!"
Here is the link to my BIOS if you want to reproduce the errors.
It only happens in the test version. I have no problems with the v1.69.10.
EDIT by Fernando: Moved this UBU report into the related thread
Bug in BIOS file. If you take the original, then there is no problem.
I do not watch, but I will check.
Added:
1)’ "File not found"
I do not know how you did the mod for AGESA and microcodes, but did not do it correctly.
You need to vaporize the problem as follows.
1) Open your file in UEFITool.
2) Find GUID DE3E049C-A218-4891-8658-5FC0FA84C788
3) Place the cursor on this GUID and make ‘Rebuild’.
4) Save BIOS file
After that, you can check with the UBU that the error no longer appears.
Hello
would it be possible to add the microcode for the platform 2066 (Skylake-X) ?
Thanks
For LGA 2066/1151v2 will be in next version 1.70.
Thanks Sonix and thanks so much for your great work 
There are any new microcodes?
Read somewhere that microcodes from nov 17 were not stable for haswell cpu.
Question, I didn’t see it in the release thread, and search hasn’t been helpful.
Is it possible to update to the latest AGESA Microcode? (990fx board, ASRock is painfully outdated with AMD AGESA OrochiPIV1.2.9.0)
And if so, how… im so lost its depressing!
Hello Net7,
it should be possible & there some friendly guys in this forum, who can do this.
But for your special AGESA Microcode v1.2.9.0 I’ve seen some benchmarks in the internet, there this MC is faster than newer ones like v1.5.0.X.
Best regards, MiMo
may I suggest a small "cosmetic" addendum to the UBU tool?
what about the option to change the image in the BIOS splash screen with a customized one (maybe something Sonix or Win-Raid inspired)?
I created a Bios for my Z97-A / USB3.1 with the latest Haswell (23) microcode. I also added Broadwell (17) so the FIT "fits" without needing a hexeditor since I propably will never have a Broadwell in this board.
UBU renamed it accordingly to the crashfree rules.
But I am not able to flash it. I formated an USB stick with Fat32 and placed the file Z97AU31.CAP in the root folder as it is on the mainboard dvd but no luck. I also created a DVD with it (since i have no cds left) and the result was the same (for the dvd version I also added new versions for all option roms)
When I try to flash it directly from the Bios I get a warning that this is not a proper Bios file, probably because of signature issues?
What can I do?
any USB flashback button on mobo?
@SoniX
I am trying to understand why this happen:
I have a mod version of my BIOS where the AGESA module (AmdAgesaDxeDriver) was updated from v1.5.0.0 to v1.5.0.7. When i open it with any regular version of UBU, i get a report that v1.5.0.7 is installed, but when i open it with the test version of UBU v1.69.10.1, i get a report that v1.5.0.0 is installed instead.
Any advice why this happen?
Here is my BIOS if you want to reproduce the reports with UBU yourself.
Because AGESA is placed in different files. If you open the BIOS in UEFITool and look for the string ‘agesa’, then several files will be found.
Also, if you scan these files, you can see that AGESA is going to the manufacturer for each motherboard individually. That is, you can see the model of the motherboard.
In UBU 1.69.10.2, for Aptio4, an AGESA file containing microcodes is extracted. Previous versions extracted any file? the contents of the string “agesa”
@Margus no I followed the guide on asus website and the same is also printed in the manual.
When I burned the DVD, I notice a spin up asap after the pc starts, so I guess the crashfree seems to access it but it does not accept my bios on the stick …
maybe @SoniX can say something about it?
Thx SoniX, just used your test UBU v1.69.10_2 and updated to microcode version 23 along with the rest of the EFI drivers.
Ran like a champ!
Used the USB Flashback method on my trusty ‘old’ Asus Z87-Deluxe motherboard and it’s running smooth as glass on the Windows 10 x64 Build 17025
Updating to build 17074 as we speak…
Cheers on all the hard work you and the rest of the crew do, in making this the ‘go to’ joint for Bios modding and updating.
So don’t go having a “Meltdown” cause “In-Spectre” gadget has got you covered…

You cant flash modified bios file normal way. You can use usb flashback or flash external way. Here is tons of info how to flash modified bios might even ami own flashtool might work. I itself press on mobo button and thats it and its read from usb stick while pc is turned off so no mess. Most asus mobos have usb flashback buttons.
