Yes, some BIOS and or MMTool only allow insertion of microcodes that are certain sizes, for alignment reasons. Were you able to get it, or do you need me to upload modified microcode for you/

@BlackArchon - open that microcode in hex editor and 00 fill from 200 to 000003ff (ending right before 400), so total size is 400h / 1024kb

Thank you, I can do this by myself now. :)

All I know is MMTool allowed microcode insertion then (At 400h total size) for this BIOS @MiesMosel

Hi guys, it's me again. Today I want to edit the latest BIOS 1.50 for my Asrock N68C-GS4 FX (http://asrock.pc.cdn.bitgravity.com/BIOS...FX(1.50)ROM.zip). MC Extractor tells me that there are eleven microcodes in this BIOS:

But MMTool 3.26 only detects six of them:

So how can I update these microcodes?

@BlackArchon - they are located in different modules is why. Only three of those are detected correctly in MMTool, notice the last three info, it's all zeros

Microcodes #3-11 are located in the P6 microcode module, microcodes #1-2 are in the first module (E2). Notice the offsets in MC Extractor big difference between 2 & 3.
To mod these, you will need to extract P6 module and E2 module and hex edit each, then reinsert. With these modules extracted, dropped in MC Extractor, it will show you each microcodes exact offset so you can easily go there for hex edit

That's what I've seen, too, L'n'B.

Here for checking ASRock N68C-GS4 FX BIOS (inkl. new microcodes), BlackArchon.

I hope, you did it, too.

Hi! I'm struggling with a system that only currently has partial support for the CPU I've installed. It is a Dell XPS 720 with a Xeon E5450 (SLANQ, C0 stepping). I'm trying to add microcode to the BIOS in hopes of fixing my Windows issues but HxD cannot find a microcode file in the BIOS file to edit and neither can MCE. What exactly can I do? Is there anything I can do?

@ EvieSigma

Dell bios are usually special and i am not used to working with them. But they usually require to use PhoenixTool to modify them so you can start by finding the latest version of it.

Which Phoenix Tool? I've found the AndyP SLIC mod tool but as far as I'm aware that tool literally only mods SLICs. I can't find a working download of the old Phoenix Mod Tool as literally ever link I find to it is broken, except for one which installs but then the program doesn't work.

The CPU shows up in the BIOS but none of the Xeon functionality does and I can't boot into Windows.

@ EvieSigma

You can download the latest PhoenixTool v2.73 in this page. I tested the download links and they are both working.

If you are looking for the changelog, it seems it got messed up since the last time i saw it, but you can still see a good version of it in the post #95 in our thread.

Okay, I found the PhoenixTool but despite skimming the thread I haven't figured out how to mod microcode using it...when I used the tool I got a DUMP folder with a bunch of .ROM files, could one of those be my microcode list?

Link BIOS from Dell downloads @EvieSigma I will check it, and do one of these for you depending on what you want (Mod the BIOS, or tell you which module to modify using PhoenixTool/Hex, or other tool that works)

Here is the BIOS. I'd really appreciate it if you could mod it!

@EvieSigma - I can do, but due to the way Dell inserts microcodes into this BIOS I need more info from your end first. You are using the BIOS above currently, correct? If yes, please tell me what microcode is loaded/in-use by your current CPU.
Check with HWInfo64, in the large window select processor then CPU by name and show me the area you see here, same image from your end. This can be done with any CPU installed, Xeon or your other if you're using the other one now it's OK too.
