Hi, I do not need to see all the microcodes, but I need something to add a microcode to the bios file

@Haskeer

I tried your bios and it did the same for me: cbrom don't want to open that file.

So i updated all the microcodes manually with Hxd Editor.

Hope that help.

You can download it here.

Yeah, that's my way too. But after HxD the MCs into the BIOS, I re-insert one if the last moduls to let cbrom do the calculation of checksum.
Then the FlashTool from the BIOS don't warn me about wrong checksum.

best regards folks

Wow thank you soooooo much! Can you explane me how you did It?

What do you wanna know:
- replacing/adding microcodes with HxD,
- re-inserting option ROMs for correct checksum with CBROM or
- have a look at the microcodes with MCE?

@Haskeer
And everyone.

I updated the first post to include a quick guide how to do it with HxD Editor for those that the cbrom method can't work. It is a QUICK guide so if anyone want more precision on something then provide some feedback and i will try to improve the parts that needs it.

@Phoenix48 and @MiesMosel
thank you so much, you are awesome!!
I will try to add the microcode with HxD editor becouse in the meanwhile I found an unlocked bios.
When I have some spare time I will try it, for now I want to share that modded BIOS with you:

Hi,

Nice guide. Have a question as far as why in an old X58 bios Cbrom reports 4 different 106A4 versions when all you need is one?!

Thanks

Hello davidm71,

Platform 01, 10 and 11 (01+10) is for S.775 CPUs.
Platform 04, 40 and 44 (04+40) is for S.771 CPUs.

What is shown by MCE?
And which CPU is installed?

Regards, MiMo

Hi MiesMosel,

I am actually on a different 1366 platform. Heres the CBRom dump:

Update ID CPUID | Update ID CPUID | Update ID CPUID | Update ID CPUID
------------------| SLOT2 08 000206E6-| SLOT1 0A 000106A4-| SLOT1 0F 000106A4SLOT1 16 000106A5
SLOT1 0D 000106A4| SLOT1 0B 000106A1 | SLOT1 19 000106A2 | SLOT1 16 000206C0
SLOT1 06 000206C1| SLOT1 14 000206C2 | SLOT1 32 000206F2 |


Since I have a 920-D0 in my old X58 all I really need is the 106A5, but out of a point of curiosity I wonder why the manufacturer would
included 4 different microcode revisions for the same 106A4 CpuId? Were they just lazy I am guessing that after every MC release
they just appended it on to the list?

Thanks

@davidm71

I can make some comments on this using my GA-X58A-UD9 bios as an example as shown in the spoiler.

First, if you take a look at the 106A4 microcodes before and after the change i made, you will notice that both microcodes were not for the same platform in the original one (Platform 0 and 1). But when you make a research to update those microcodes, you realise that a microcode including both (platform 03, 0+1) didn't exist untill the year 2015 and manufacturers had no other choice than to include both microcodes in the bios up to that point in time.

Second, the original bios included 2 microcodes for the exact same platform for 206C2. So yes, sometimes manufacturers are really lazy and do things that don't make sense at all.

@Phoenix48

Ok Thanks! It makes sense now. Guess I have to start over..

Practice makes perfect..

Hi guys, I have a Dell XPS17 L702X laptop I carefully followed the guide to update the cpu microcodes but in the last passage with cbrom after pressing enter, the cursor remains flashing .... where am I wrong?
