Please update the 1-st post with the links to various CBROM versions, http://www.lejabeach.com/CBROM.html for example.

@Gregory_Tumanyan

Links are repaired.

423

There is no CBROM V1.55 in your collection. What version should be used with Gigabyte BIOSes?

424

@Gregory_Tumanyan

You are right. Some versions were missing in this file. I fixed it. You can download it again.

425


Depends on mainboard model. Which one exactly do you have?

426



P55A-UD3R

427

@Gregory_Tumanyan

CBROM 1.55 is the one you should use. Anything newer will try to rearrange the first half of the Bios and, as a results, the flasher wonā€™t accept to flash it.

428

I faced the same issue as @Skorbin with 1.55. MC Extractor sees the codes but the flasher doesnā€™t accept the modded image.

429

@Gregory_Tumanyan

If everything is perfect with MCExtractor then i suspect this could be a checksum error. Restore the checksum by replacing the last module in the Bios with CBROM. This will assure that the checksum is correctly restored and it should flash.

Hi @Lost_N_BIOS

I have mainboard named is Gigabyte GA-M56S-S3 for 7 year ago, now i decided to upgrade CPU from Athlon X2 to Phenom II X4 960T Black Edition, but my mainboardā€™s bios not recogzine this CPU correctlyā€¦ event if i update to lastest bios version of this mainboardā€¦
I just went to Gigabyte website to check CPU support list of my mainboard, it support only to Phenom II X4 955ā€¦
Could you please help me to mod lastest bios file (M56SS3.F6h) for support Phenom II X4 960T?

Thank and best regards!

431

@anhnga

You can try to add support for 960T by adding in the Bios the CPU microcode for it which is the microcode with the CPUID# 100FA0

432


Thank! Could you please help me to mod bios for my mainboardā€¦
I tried, but not successfullā€¦

433


My mainboard can detect Phenom 960T correctly nameā€¦ but it not show correct CPU clock. but it run well with slowly speed
The CPU clock alway lock in 800mhzā€¦

Did you know how to fix that? or Could you mod this mainboardā€™s bios for me? Please!

Thank!

434


Oop! I forgot the link of my mainboard lastest biosā€¦
PS: this is link of lastest bios: http://download.gigabyte.com/FileList/BIā€¦m56s-s3_f6h.exe

@anhnga
I modded your bios file with the newest Āµcode ā€œcpu00100FA0_ver010000DC_2011-10-24_710BF12Aā€ and corrected the checksum.
Nothing other changed.

!!! I did it with the best intentions, but I canā€™t guarantee that it will work. I do not offer any warranty. !!!

OK, I will try to flash your moded bios on my mainboard and will let you know it working or not.

Thank, best regards!

Hi, Iā€™ve got the GA-M56S-S3 motherboard as post before and I changed the processor to Phenom II X4 955 HDZ955FBK4DGM which is not supported by my motherboard and it stuck at 800MHz. Could you modify the BIOS file for me to add support of this processor by modifying CPU microcode CPUID#00100F43? I spent a lot of time of trying to make it work, but I failedā€¦

Hi sir,
I am a new member on forum.
Now I just bought a PC with specs:
CPU: Intel CC150 3.5 GHz
Mobo: MSI IPC MS-98K9 (Industrial motherboard)
Ram: ECC UDIMM Bus 2666 32GB (2x16)
GPU: Nvidia GT730 DDR5 4GB

When I boot to OS (Windows, Ubuntu, WinPE,ā€¦) both of all are stuck at logo OS screen.

With Ubuntu: has a line: " [Firmware Bug]: TSC_DEADLINE disabled due to Errata please update microcode to version 0x52 (or later) "

and it stuck on here ā€¦ :frowning:

Now I canā€™t boot to any OSā€¦ Pls help me :frowning:
