Edit

I don't see the problem in your image? Except maybe steps/method? First command I see you add one microcode to a NCPUCode.bin file, then next command you add 20+ microcodes to NCPUCode.bin file, you can do all that at once.
Next command I see add back NCPUCode.bin to BIOS, without any error shown. But the process is incomplete for someone else to check based on images alone, we'd need to see cbrom bios.bin /d before and after this mod to see how BIOS looked before/after.

My mistake was not having the microcodes in the same folder where I was launching the code

my mc size is changed from 217kb to 361kb but i can't watch microcode in cbrom, only in mce.
is this normal?

Yes, size change is normal if you added more or larger microcodes than originally contained. Does everything look good in MCE?

Does MC codes show in table at bottom of cbrom output in original and after? Not sure what BIOS you are editing there, some BIOS you have to use older cbrom.

You should keep your cbrom labeled correct so you know what is what. I see your last command you entered cbrom232, but actual cbrom that ran that command is 115 version not 232

Guys please tell me, MC Extractor v1.24.0 r82 indicated that for my BIOS the microcode has become obsolete:
cpu1067A_plat11_ver00000A0B_2010-09-28_PRD_B007E7E3.bin
cpu10676_plat01_ver0000060F_2010-09-29_PRD_8FE1A246.bin
cpu10676_plat10_ver0000060F_2010-09-29_PRD_8FE1A237.bin

in the folder CPUMicrocodes-master there are the following microcodes:
cpu1067A_plat44_ver00000A0E_2015-07-29_PRD_A3107D75.bin
cpu1067A_platB1_ver00000A0E_2015-07-29_PRD_59BF808E.bin
cpu10676_plat04_ver00000612_2015-08-02_PRD_AEAA6CC1.bin
cpu10676_plat40_ver00000612_2015-08-02_PRD_B6F50E9C.bin
cpu10676_plat44_ver0000060F_2010-09-29_PRD_8FE1A203.bin
cpu10676_plat54_ver0000060C_2008-01-19_PRD_FBAC0F19.bin
cpu10676_plat91_ver00000612_2015-08-02_PRD_1750A2A6.bin

Which one of them do I need a microcode.

Did I understand correctly that for the obsolete:
cpu1067A_plat11_ver00000A0B_2010-09-28_PRD_B007E7E3.bin should be replaced by cpu1067A_platB1_ver00000A0E_2015-07-29_PRD_59BF808E.bin, and
cpu10676_plat01_ver0000060F_2010-09-29_PRD_8FE1A246.bin and cpu10676_plat10_ver0000060F_2010-09-29_PRD_8FE1A237.bin must be replaced by cpu10676_plat91_ver00000612_2015-08-02_PRD_1750A2A6.bin

Hello Dagal,

yes, you are right.

This is for S.775 CPU (C2D, C2Q):
platform 0x11 = platform 0, 4

You can use B1 instead with new microcode:
platform 0xB1 = platform 0, 4, 5, 7


platform 0x91 = platform 0, 4, 7 -> so it can be used instead of
platform 0x10 = platform 4
platform 0x01 = platform 0


And this is for S.771 CPU (XEON):
platform 0x04, 0x40 and 0x44 = 2, 6

regards, MiMo

@MiesMosel!
Hello! Many thanks for the detailed response!

why opening the file bios with a hex editor I find 2 ncpucode.bin in which the first is preceded by Y?

I can't copy an entire complete ncpucode create by me?

I think it's better to exchange the MCs with HxD in a correct way & fix the checksum, then to copy more and more MCs into the BIOS file.

I use always cbrom to update but i want change all mc that i had save in a one ncpucode.bin

I do it that way pipes80, then check with MC Extractor once done and make sure you do not get the duplicate/badly pack errro mentioned in the FAQ #1, if so you will need to correct via the guides outlined method.
Some cbrom will not insert properly, depending on BIOS, it may not insert at all, or may double ncpucode size in BIOS, in those instances it's wrong cbrom try another.

If you use CBROM for inserting, I guess you to (extract and) release the whole NCPUCODE.BIN before inserting new one.

@pipes80
Which BIOS we talk about in your case?

I do not extract/release usually. I build new one from scratch and overwrite current one in place.
