Morku u have a haswell cpu so put the microde broadwell 17 (the last before spectre patch) and haswell 23 witch provide the spectre patch and u dont need to hex edit anything.

Except u try all of them because u want to learn.



Also i have tried personally the microcode 23 with the asrock z97 and it have problems. WHEA errors in stock settings and i am not the only one. Asus seem to work. U have better to use 22 witch i use and i have no problems.

@ Morku
In a hex it is necessary to read mirror.
We need - FFF39130 this 3091F3FF
Change to - FFF3A130 this 30A1F3FF

In your case, only 1 byte - 91 on A1
The following 2 lines fill FF.

@boombastik
propably the best option, since there is no plan ever to put in Broadwell :)
And yes, just noticed that news: https://newsroom.intel.com/news/intel-se...-reboot-issues/
Well done, Intel.

@SoniX
Ah, I should have notice that :)
So just in case, this is right now?


And do I have to copy body back in stock bios before applying cpu microcode or after in the already modded bios

Thanks a lot again, we'll come to a conclusion :)

I'm newbie for modding BIOS. I have Gigabyte H61MA-D3V (REV 2.0) with a Intel i5-3450 CPU.

I think it's difficult for manufacturer to have BIOS update for Spectre/Meltdown bug on this motherboard, so I want to update microcode myself. I searched Intel site and found there is a microcode update for this CPU with date 2018/1/8. I knew UBU can be used to update microcode, but not sure how to do it.

How do I use UBU to write the updated microcode got from website of Intel into my current BIOS? (ver. F7c)

Didn't Intel also release CPU Microcode for LGA1155???

Thanks a lot for the great tool. :-)

But is it really a good idea to hand out the current Intel Microcode Security Updates without any warning? I read a lot of users having problems of unstable system and also I saw this: https://www.wsj.com/articles/intel-warns...uggy-1515715212

Hi Fernando,
Does "UBU Tool" compatible with Lenovo Yoga 2 Pro (20266) - BIOS 76CN43WW (2015/08/12)?
I would like to update latest Intel's microcode for i7 4500U (Haswell) but don't know the correct steps.
Regards,

Random question that might deserve its own thread...

A long while back I recall talking to or seeing talk regarding the AMD RAID ROM's having a "license level" that each MFG pays/license's (I think it was an ASUS support ticket, as it was not AMD made but licensed from another MFG), I was complaining about why a competitors board with the same Chipset was able to do RAID 6 or maybe RAID 10 but mine couldn't...

SO, the question is, the RAID rom upgrades that are in UBU, they have a modified license level? AND what might make it require a whole new thread, is that possible? (understandably not distributable)

Ya, looking at the manual it seems some had different license level's in the RAID rom! so, above question :D

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

I do not watch, but I will check.

Added:
1)' "File not found"
